Oi Yannes,

Para funcionar com Java 11 é preciso atualizar esse arquivo server.jar pois algumas bibliotecas foram removidas nas versões mais recente do Java. Estou vendo isso com o instrutor de curso.

No entanto tem solução baseado no Docker, mas precisa ter Docker Desktop instalado.

Uma vez instalado basta executar o comando abaixo que sobe um container baseado na imagem do java 8 e tbm já roda o servidor (o server.jar precisa estar na mesma pasta):

docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp -p 8080:8080 openjdk:8-jre java  -jar server.jar

Na primeira execução demora um pouco pois precisa baixar a imagem, a partir dai é bem rápido.

Eu acho que vale a pena investir um pouco no Docker pois ele é muito muito útil. De qq forma estou vendo com o instrutor do curso a atualização do arquivo JAR.

Oi Yannes,

acho que faltou uma parte do comando (é comprido mesmo, faz um scroll para chegar até o fim):

docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp -p 8080:8080 openjdk:8-jre java -jar server.jar

Pelo que eu vi na sua mensagem faltou o -jar server.jar no final, mas o docker já rodou!!

Talvez eu me expressei mal, mas vc precisa executar o comando no mesmo lugar onde está o server.jar.

Por exemplo, coloque o server.jar na pasta Documentos do seu Mac. Depois abra um terminal e digite:

cd Documents

Verifique se o JAR realmente está nessa pasta. Para tal digite comando:

ls -l

que deve listar todos os arquivos da pasta atual. Se vc encontrou o server.jar, digite o comando Docker:

docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp -p 8080:8080 openjdk:8-jre java -jar server.jar

ok?
