我最近将项目构建从 ant 切换到 maven 和 m2e，这工作正常，现在突然每次我保存文件时，构建工作区都会占用大量时间，大约 5 到 10 秒，以前是当我刚刚保存一个文件时，我什至从未注意到 eclipse 做任何事情。

我猜测 m2e 在增量构建期间正在做一些事情，这会减慢速度。我不知道是什么导致了减速。我正在寻找可以尝试找出这种放缓的原因的东西。

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 个罐子和一场战争。这是按照标准的 Maven 层次结构排列的。

更新：在非常快的机器上，Project clean all 需要大约 30 到 85 秒的挂钟时间。Web 项目本身需要大约 1 秒的时间来构建，我不知道问题出在 m2e 还是其他地方。

更新：保存 .java 文件会导致工作区重建，其长度可能为 0 到 15 秒，以不可预知的方式。

更新：我正在使用具有工作区工件分辨率的 m2e-wtp 扩展。

更新： m2e 日志文件的一些输出

更新： 这原来是 Eclipse STS 中的弹簧工具错误且缓慢，摆脱弹簧项目性质解决了问题。似乎 Spring 源代码团队知道这些问题正在修复，请参阅下面的我的答案以获取一些链接。

经过一番摸索，结果发现 Spring Tool Suite 3.1 是问题所在，一旦我从项目工作区中删除了弹簧性质，构建时间从 30 - 90 秒降至不到 3 秒。

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

  <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" />

我可以在此输出中获得输出，.metadata/.plugins/org.eclipse.m2e.logback.configuration/0.log该输出具有时间戳，并且当 .java 文件获取时，m2e 似乎不止一次运行。

我一直无法弄清楚如何使用日志文件中的信息来解决我的问题，我非常接近放弃 m2e。我在这里发布此信息，以防它可能对其他人有用。
