我最近把一个项目构建从ant切换到了maven和m2e，这是正常的，现在每次我保存一个文件时，构建工作空间都会占用很多时间--大约5到10秒--过去我甚至不用花时间就可以在保存文件时注意到eclipse做任何事情。

我猜m2e在增量构建过程中正在做一些事情，正在减慢速度。我不知道是什么导致了经济放缓。我正在寻找一些东西，我可以尝试找出这一放缓的原因。

我可以采取哪些选择或步骤来帮助我找出这个问题的原因。

更新：--这是一个多模块项目，有17个模块、16个jars和一个war。这被安排在标准的maven层次结构中。

更新：项目清理工作在非常快的机器上花费大约30到85秒的时间。web项目本身需要大约1秒的时间来构建，我无法判断问题是在m2e中还是在其他地方。

更新：保存.java文件会导致工作空间重建，它可以以一种不可预测的方式从0到15秒不等。

更新:我正在使用带有工作区工件解析的m2e-wtp扩展。

更新：来自m2e日志文件的一些输出

更新：这是eclipse中的spring工具，错误多，速度慢，解决了这个问题。看来spring源代码团队已经意识到这些问题正在进行修复，请参阅下面的答案以获得一些链接。

经过大量的抓挠之后，Spring 3.1才是问题所在，一旦我从项目工作区中删除了spring特性，构建时间就从30-90秒下降到不到3秒。

当我将.metadata/.plugins/org.eclipse.m2e.logback.configuration/更改为输出调试信息时，我发现它包含了m2e logging logback.1.2.0.20120903-1050.xml的配置文件。

  <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中获得输出，这个输出有时间戳，当.java文件获取时，似乎m2e运行了不止一次。

我还没有找到如何使用日志文件中的信息来解决我的问题，而且我已经接近放弃m2e了。我在这里张贴这个信息，以防它可能对其他人有用。
