Java 未能执行目标org.apache.maven.plugins:maven编译器plugin:2.3.2

我知道这是因为我的~/.m2/存储库中有一个或多个jar文件损坏，但我无法确定哪些jar文件已损坏，或者哪些jar需要删除并重新下载

你使用哪个Maven版本？哪个Java版本？（'Unsupported major.minor version 52.0'）？@khmarbaise嗯，当我将maven编译器插件的maven依赖项更新到其最新版本时，我的问题得到了解决，即在pom.xml中将版本从2.3.2更改为3.1。它现在成功地构建在Java7和Java8上。对于maven，我正在使用最新的m2e eclipse插件。您更新了maven编译器插件的依赖项吗？为什么不更新maven编译器插件本身呢？你更新了哪个依赖项？@khmarbaise我是说，我将maven编译器插件本身更新到了最新版本。所有其他maven编译器插件依赖项显然都是自动更新的。Ok。谢谢你把它清理干净。
