Eclipse在大型Maven项目中依赖于"验证启动属性"

Question

我正在使用Eclipse开发一个大型Maven项目(几十个依赖项).当我尝试运行单元测试时,我看到暂停大约一分钟,而状态显示"验证启动属性".观察Eclipse在Process Monitor中的活动,我看到Maven存储库中对各种锁和jar的大量文件访问.看起来Eclipse会覆盖我的项目所依赖的每个JAR.一旦完成该文件访问,就开始实际测试.

我知道在" 启动运行配置时,为什么Eclipse挂起了57%的状态"验证启动属性... ",并且我遵循了建议的修复程序.我认为Eclipse通过遍历每一个JAR来做它应该做的事情.我的问题是,如何在Eclipse或Maven中禁用该行为？

我在Windows 7上使用Eclipse Luna,m2e版本1.5.0.20140606

编辑:

下面是我在Process Monitor中看到的示例:

简而言之,我们花费大约10秒钟进行合理的活动,例如检查Java和JAR文件的状态,然后我们花费大约40秒锁定Maven repo并读取POM文件.

为什么eclipse会这样做？我需要改变什么来阻止它？

Answer 1

到目前为止，唯一有帮助的是关闭我工作区中的许多项目。当我的工作空间有 30 个 Maven 依赖项时，单元测试需要 30 多秒才能启动。当我关闭这些项目并强制 Eclipse 转到本地存储库时，单元测试的启动需要 5 秒。

我发现开始时间和“外部”依赖关系之间没有相关性。只有“内部”（在工作区和打开的）依赖关系很重要。
