• 我有一个遗留的Java 5项目,至少在2017年12月31日之前仍然会保留.
• 我的默认系统JDK是1.8.
• 还安装了JDK 1.5,如在Ubuntu 12.04中安装Java 5和https://askubuntu.com/questions/522523/how-to-install-java-1-5-jdk-in-ubuntu中所述.

POM包含(如/sf/answers/1567929891/中所述):

<profile>

  <!--
    NOTE
    Make sure to set the environment variable JAVA5_HOME
    to your JDK 1.5 HOME when using this profile.

  </build>
</profile>

$JAVA5_HOME 设置:

• echo $JAVA5_HOME
/usr/lib/jvm/jdk1.5.0_22

据我所知,Java + Maven的神奇之处在于,它应该是maven-compiler-plugin指示JDK 1.8伪装成JDK 1.5并使用Java 5引导类路径的有效咒语.

根据为什么javac在@Override注释上失败,JDK 1.5将不允许接口的已 …

我正在尝试构建一个 Jenkins 插件，mvn install -Dmaven.test.skip=true但失败并出现以下错误：
