Acabei de instalar o NetBeans 8.2 e tudo pareceu correr bem. Eu fiz quase 100% de default, exceto removendo um ou dois módulos que eu nunca precisaria, e alterando o espaço de trabalho padrão na primeira vez que ele rodou.

Agora não fará nada. Quando clico no comando File->New Project , nada acontece. Quando clico em vários outros comandos, simplesmente nada acontece.

O log do IDE mostra um rastreamento de pilha após eu tentar criar um projeto. Este é esse traço:

Por favor, esclareça a versão do jdk. No meu caso eu uso a próxima solução: O NetBeans 8.2 não é compatível com o jdk 9. Estou temporariamente renomeando o diretório jdk-9 e mudo o jdkhome padrão na reinicialização. Ou altere o netbeans_jdkhome em etc \ netbeans.conf.

Talvez isso ajude também.

O JDK 9 ainda não funciona com o NetBeans 8.2. Você precisa de pelo menos JDK 8 , JRE 8 .

Abra uma linha de comando e digite "javac -version" para ver a versão do JDK.

No netbeans, sob a aba "tools" escolha "java-platforms" e adicione o JDK 8 como padrão através de "add Platform" (pasta jdk). Ou tente reinstalar o netbeans e escolher o JDK 8 durante a instalação.
