Eclipse Juno 使用“Maven Project Builder”构建错误答案

【问题标题】：Eclipse Juno build error with "Maven Project Builder"Eclipse Juno 使用“Maven Project Builder”构建错误
【发布时间】：2013-01-19 11:03:44
【问题描述】：

当我尝试清理和构建我的 Maven 项目时，我收到以下错误：

Errors occurred during the build.
Errors running builder 'Maven Project Builder' on project '(Hid Project Name)'.
org/apache/maven/project/MavenProject
Errors running builder 'Maven Project Builder' on project '(Hid Project Name)'.
org/apache/maven/project/MavenProject

与 clean all 过程类似，它会抛出以下内容：

Errors occurred during the build.
Errors running builder 'Maven Project Builder' on project '(Hid Project Name)'.
loader constraint violation: loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) previously initiated loading for a different type with name "org/apache/maven/plugin/MojoExecution"

任何想法是什么原因造成的？

【解决方案1】：

如果您使用的是外部 maven，请检查是否已选中

还可以尝试删除 .m2 并检查那里的设置文件是否指向 localRepository 标记中的正确位置

C:\Users\sunny.m2\repository

投票赞成成为 3 年内唯一回复此问题的人！我认为这值得一个徽章。

【解决方案2】：

除了 Maven 安装点，还要检查 Maven 的“用户设置”。我的指向一个默认位置，但我在某个地方也有导致问题的 settings.xml。

【解决方案3】：

我通过更正 JDK 的 eclipse (eclipse.ini) vm 值来修复我的问题。
