Question

我最近将项目构建从ant切换到了maven和m2e，这工作正常，现在突然每次我保存文件时，建筑工作区占用了大约5到10秒的时间，它过去，当我刚刚保存文件时，我从未注意到eclipse会做任何事情。

我猜测m2e在增量构建期间正在做一些事情，这会减慢事情的速度。我不知道是什么导致了经济放缓。我正在寻找可以试图找出这种放缓原因的事情。

我可以采取哪些选项或步骤来帮助我找出导致此问题的原因。

更新：这是一个多模块项目，包含17个模块16个罐子和一个战争。这是在标准maven层次结构中安排的。

更新：项目清理在非常快的机器上占用大约30到85秒的挂钟时间。 Web项目本身需要大约1秒才能构建，我无法判断问题是在m2e还是在其他地方。

UPDATE：保存.java文件会导致工作区重建，可能会以不可预测的方式重建0到15秒。

更新：我正在使用带有工作区工件分辨率的m2e-wtp扩展。

更新：来自m2e

更新这原来是日食STS中的弹簧工具越来越慢，摆脱弹簧项目性质修复问题。似乎Spring源团队意识到这些问题正在修复，请参阅下面的答案以获取一些链接。

Answer 1

经过多次努力之后，事实证明Spring Tool Suite 3.1存在问题，一旦我从项目工作空间中移除弹簧性质，构建时间从30-90秒减少到不到3秒。

https://issuetracker.springsource.com/browse/STS-3036
https://issuetracker.springsource.com/browse/STS-3017
https://issuetracker.springsource.com/browse/STS-3054有许多与性能相关的issuse的子任务。

我发现.metadata/.plugins/org.eclipse.m2e.logback.configuration/包含m2e logging logback.1.2.0.20120903-1050.xml的配置文件，当我更改它以打印出调试信息时

  <root level="DEBUG">
    <appender-ref ref="FILE" />
    <appender-ref ref="STDOUT" />
    <appender-ref ref="EclipseLog" />
    <appender-ref ref="MavenConsoleLog" />
  </root>

  <logger name="com.ning.http.client" level="DEBUG" />

我可以在.metadata/.plugins/org.eclipse.m2e.logback.configuration/0.log中输出此输出有时间戳，并且看起来m2e在.java文件获取时运行多次。

我无法弄清楚如何使用日志文件中的信息来解决我的问题，而且我非常接近放弃m2e。我在这里发布这个信息，以防它可能对其他人有用。

如何确定为什么m2e会降低日食的速度？
