詹金斯和maven-compiler-plugin？

Question

我在配置 Jenkins 时遇到问题，我正在从 tomcat7 [在 ubuntu 上] [从 apache 下载，未通过 apt-get 安装] 运行 jenkins。我已经从 Oracle 安装了 java。当我想构建一个项目时，maven 说 maven-compiler-plugin 导致问题：

    org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project npa: Compilation failure
    at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:213)

at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:320)
at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:156)

关键是我没有在这个版本中使用 maven-compiler-plugin，我什至没有在任何 POM 中声明这个插件！我自己无法在 pom 中添加任何内容[不要问为什么]

编辑： 全栈 [maven 中的 -X 选项]

Answer 1

代码无法编译。 Maven 默认包含编译器插件。查看错误消息的其余部分以找出代码未编译的原因。可能与不兼容的 Java 版本有关。

编辑：您使用的是旧版本的编译器插件，默认为 Java 1.3 选项，这就是它无法编译的原因。

我怀疑 Jenkins 可能指向 Maven 2（请参阅此问题 Maven : error: generics are not supported in -source 1.3 , I am using 1.6）。确保 Jenkins 使用的是正确的 Maven 3 安装。
