我在开发中使用了 Tomcat 7 和 JDK 7。当我clean package cargo:redeploy在 Juno Eclipse 中执行这个 maven 目标时，它会显示这个错误。希望能从你那里看到一些线索。

您正在将此配置用于 maven 编译器插件：

<compilerArguments>
  <endorseddirs>${endorsed.dir}</endorseddirs>
</compilerArguments>

但似乎您没有在${endorsed.dir}任何地方设置变量。-endorseddirs所以Maven在java命令行中添加了一个空参数。

因此，您应该compilerArguments从插件配置中删除条目或正确设置变量。
