Problema na importação do projeto

Bom dia a todos!

Ao fazer a importação do projeto, vejo que todos os imports estão com erro exemplo: javax.persistence, org.springframework entre outros que possam existir.

Que procedimento devo seguir para regularizar esses imports?

Encarecidamente quem puder me apoiar na solução desse problema agradeço antecipadamente.

Atte., Vicente

Olá Vicente, tudo bem?

Qual seria o erro que ele aparece? Talvez isso seja por conta das versão do Java que foi usada no projeto e a versão que está instalada no seu PC.

Bom dia, Rafael!

Estou usando o java na versão 1.7.0_79, eclipse neon, apache maven 3.3.9.

Segue abaixo algumas das mensagens de compilação:

- The declared package "br.com.caelum" does not match the expected package "main.java.br.com.caelum";
- The import br cannot be resolved
- The import org.springframework cannot be resolved;
- The import javax.persistence cannot be resolved;
- The import javax.servlet cannot be resolved.

Parece que estão faltando as bibliotecas necessárias.

Atte., Vicente

Oi Vicente,

Me parece ser algum conflito no nome do pacote. Minha sugestão seria remover os pacotes e arquivos do projeto e fazer a importação dessa:

  1. Remover os arquivos internos do projeto
  2. Clique com o botão direito do mouse no projeto
  3. Clicar em Import
  4. Digite: File System
  5. Escolha o diretório onde salvou o projeto e posteriormente marque na aba de baixo todas as opções que pertencem ao projeto.
  6. Vai clicando em Next e Posteriormente em Finish

Feito isso o projeto deve ter sido importado e acredito que o erro vai desaparecer.

Espero que dê certo!

Boa tarde, Rafael!

Segui a dica, mas ainda não foi desta vez. Após mover os arquivos e reimportá-los da pasta original do projeto, parece que tudo ia dá certo e quando se olha no projeto no eclipse percebe-se que nada foi importado, na aba "progress" ao lado da aba "console" do eclipse é possível ver "Building workspace (Sleeping)" aí se tem a falsa impressão que o eclipse ainda está fazendo os imports e depois de um longo período de espera, observa-se que não foram importados quaisquer arquivos.

Atte., Vicente

Oi Vicente,

Estranho essa mensagem, na aba Problems (fica embaixo junto com a aba console) aparece alguma mensagem adicional? Minha próxima sugestão seria remover o projeto por completo (clicando em Delete e depois em Delete Project Contents on Disk). Depois selecione Java Project e tente repetir a importação mencionada acima.

Espero que dê certo!

Bom dia, Rafael! Segui sua dica, mas infelizmente ainda não consegui estabelecer meu ambiente de desenvolvimento.

Observação: como estou usando o eclipse neon ajustei as variáveis de ambiente do java e maven para o JDK 1.8.0_111, testei a instalação via prompt e estão funcionando corretamente.

Segue abaixo as bibliotecas e os alguns dos erros identificados;

Oi Vicente,

Pelo que vi, parece que as dependência do maven não estão sendo importadas no projeto. Tente fazer o seguinte, clique com o botão direito do mouse no projeto e clique em Configure -> Convert to Maven Project. Tudo ocorrendo bem, você deverá ver em seu projeto o Maven Dependencies com as jars.

Abs

Boa tarde, Rafael! Estou usando a versão neon do eclipse e nessa versão eu não tenho em Configure a opção Convert to Maven Project

Configure -> Convert to JPA Project...
              Enable as Cloud Foundry App
              Convert to Plug-in Projects...

Mas eu tenho a opção de menu Maven na qual tem algumas opções conforme abaixo:

Maven -> Add Dependency (obrigatório informar: Group Id e Artfact Id)
          Add Plugin
          New Maven Module Project
          Update Project...
          Select Maven Profiles...

Observação: tentei a opção Update Project e achei que fosse funcionar, pois foi feito os downloads, embora com alguns erros conforme abaixo, mas infelizmente ainda não foi desta vez o funcionamento.

Oi Vicente,

O Neon parece que mudou algumas configurações com relação ao Luna (versão que eu tenho). Uma dúvida, a primeira vez que você importou o projeto e deu o problema você escolheu a opção Existing Maven Projects? Porque quando escolhemos importar de um projeto maven ele já colocaria todas as dependências. Para poder fazer a importação do projeto maven, a importação já colocará todos os arquivos dentro do projeto chamado projeto-jpa-2 (nome do arquivo do download), não precisando assim criar um projeto antes de importar.

Para isso, clique com o botão direito na área de projetos -> Existing Maven Projects -> Browse (local onde você salvou o arquivo do projeto....deverá aparecer o pom.xml). Ao selecionar o pom.xml e clicando em Finish, o projeto com o nome projeto-jpa-2 deverá ser importado com todas as dependências. Tudo ocorrendo bem, devemos ter o Maven Dependencies em nosso projeto. Consegue rever essa etapa?

Abs

Bom dia, Rafael! Era justamente isso que eu fazia para importar o projeto, mas para desencargo de consciência, fiz a importação seguindo atentamente a sua orientação, e infelizmente continua o mesmo problema.

Bom dia Vicente,

As dependências do maven apareceram no projeto depois da importação? Os seus pacotes ainda estão como main.java.br.caelum....? Se estiverem, vá nos pacotes e clique com o botão direito -> Refactor -> Rename e mude o nome para que todos fiquem br.caelum....

Se mesmo assim ainda estiver com problemas de importação, vá até a classe Configurador passe o mouse nas anotações, deverá aparecer uma opção Fix Project Setup. Clicando nela deverá corrigir esses probrlemas de configurações, não devemos ter mais erros.

Espero que dê certo!

Abs

Bom dia, Rafael! As coisas andam um pouquinho difícil, mas em algum momento chegaremos à solução para ficar de exemplo para outros.

Segui sua orientação do primeiro parágrafo e não funcionou; Na orientação do segundo parágrafo na classe Configurador ao clicar na Opção Fix Project Setup aparece uma pop-up com os dizeres: "No proposals have been found to fix the unresolvable reference to 'EnableTransactionManagement' Click here to manually configure the build path of project 'projeto-jpa-2'. " ao clicar na opção sugerida aparece na aba "Order and Export" checkbox uma com "projeto-jpa-2/src" e outra com "JRE System Library [JavaSE-1.8]" selecionei a primeira e cliquei em apply e em OK e o erro continua lá sem qualquer mudança.

Oi Vicente

Bem complicada a situação hein, posso te pedir para fazer algumas coisas ?

  • Apaga a sua .m2, essa pasta fica dentro da sua pasta de usuário.
  • Apaga o seu projeto pelo eclipse ( marca a opção Delete project contents on disk(cannot be undone))
  • Na parte de Project Explorer clica com o botão direito seleciona a opção import... dentro de import . Digita Maven na tela de import, vai aparecer várias opções, você vai escolher a opção Existing maven project. Mostre para o eclipse qual é a pasta do projeto e da um finish.
  • Feito isso o eclipse vai importar o projeto, e baixar todos os jars necessários para o projeto funcionar.

Por favor, depois de fazer isso me informe se deu certo.

abraço

Não funcionou ainda. Não sei se é importante, mas percebo que nesta importação a pasta ".m2" não foi recriada. Testei o Maven novamente via prompt e aparentemente está funcionando. Veja o teste:

Oi vicente

Faz um mvn clean install na pasta do projeto, usando o prompt.

Observe se o maven vai baixar os jars do projeto.

Meu caro não funcionou, mas parece mesmo que é o tal do Maven.

Na verdade parece algum problema na sua conexão Vicente. Consegue fazer o mesmo comando em outra conexão ?

Bom dia, Caio! Alterei o arquivo "settings" do Maven incluindo as informações do servidor proxy da minha rede e executei novamente o comando "mvn clean install". Veja o resultado abaixo. Importei novamente o projeto: "projeto-jpa-2" e os erros ainda permanecem.

Oi Vicente

Descobimos um problema, agora os jars estão devidamentes baixados na sua máquina, agora temos outro problema, que é referente ao erro inicial:

- The declared package "br.com.caelum" does not match the expected package "main.java.br.com.caelum";
- The import br cannot be resolved
- The import org.springframework cannot be resolved;
- The import javax.persistence cannot be resolved;
- The import javax.servlet cannot be resolved.

Certo ? Chuto que esse problema está acontecendo pois seu eclipse não sabe qual é a src folder do projeto, para confirmar clique com o direito no projeto em project explorer, vai em Build Path, Configure Build Path. Na janela de properties em Java build Path vai ter uma aba que se chama Source, as duas sources principais qeu é o main e o test tem que ter esse caminho : projeto-jpa-2/src/main/java e projeto-jpa-2/src/test/java

Se for diferente basta você clicar em edit e colocar o caminho do folder src/main/java e src/test/java

Pode verificar ?

abraço

Bom dia, Caio! Na aba Source da janela de Properties, temos apenas a pasta projeto-jpa-2/src. Quando clicamos no botão Edit... abre uma janela de edição com a informação "Source Folder" Edit source Folder Folder name: src

Conteúdo da pasta projeto-jpa-2/src na aba Source
projeto-jpa-2/src
    Included: (All)
    Excluded: (None)
    Native library location: (None)
    Ignore optional compile problems: No

Muda o Folder name para src/main/java Vicente, depois faz um refresh no projeto.

abraço

Boa tarde, Caio!! Segui a orientação e a situação agora é:

Na aba Source da janela de Properties, temos:
projeto-jpa-2/src/main/java
    Included: (All)
    Excluded: (None)
    Native library location: (None)
    Ignore optional compile problems: No

projeto-jpa-2/src/teste/java
    Included: (All)
    Excluded: (None)
    Native library location: (None)
    Ignore optional compile problems: No
  • Na área Explorer do eclipse temos:
projeto-jpa-2/
    src/main/java
        br.com.caelum
        br.com.caelum.controller
        br.com.caelum.dao
        br.com.caelum.model
    src/teste/java
    JRE System Library [JavaSE-1.8.0]
    build
    src
        main
        teste
    target
        m2e-wtp
        pom.xml
Erros mais comuns de imports:
    - The import org.springframework cannot be resolved;
    - The import javax.persistence cannot be resolved;
    - The import javax.servlet cannot be resolved;
    - ReloadableResourceBundleMessageSource cannot be resolved to a type;

Clica com o direito na pasta do projeto, vai em Maven, e escolha a opção update project, tenha certeza que o projeto está marcado no checkbox, e clique em ok.

Feito conforme vossa orientação e com toda a certeza de que o checkbox do projeto estava marcado. Infelizmente não funcionou.

Observação: desde que deletamos pasta ".m2", ela não mais foi recriada. Isso é normal?

Oi Vicente

Não é normal, na pasta .m2 fica gravado todos os jars que o maven baixa,

Tenta fazer um mvn clean install novamente. Se não criar a .m2 você me avisa.

Bom dia, Caio!

Não está criando a pasta ".m2" porque na opção de menu

Window->Preferences->Installations

Estamos apontando para

C:\apache-maven-3.3.9

e na opção de menu

Window->Preferences->Maven->User Setings

Estamos apontando para

C:\apache-maven-3.3.9\conf\settings.xml

Caso voltemos a usar as opções default para as opções

Window->Preferences->Installations = default
Window->Preferences->Maven->User Setings = D:\Users\88990230\.m2\repository

Resolve o problema de criação da pasta ".m2", mas volta ter o erro abaixo na importação do projeto:

Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6
Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6

Observação: também foi copiado o arquivo C:\apache-maven-3.3.9\conf\settings.xml, (o qual está funcionando) para a pasta D:\Users\88990230.m2\repository, mas a tentativa foi em vão. Os erros continuam.

Eu acho que os jars não estão baixados. Veja se tem algo na sua .m2\repository\javax\javaee-web-api\7.0

solução

Segue conteúdo da pasta: .m2\repository\javax\javaee-web-api\7.0

  • javaee-web-api-7.0.jar;
  • javaee-web-api-7.0.pom.

Todas as demais subpastas: c3p0, jstl, log4j, mysql e org da pasta .m2 também tem seus respectivos jars.
