Preferences lastWarOutDir is not updated

A small annoyance. The lastWarOutDir is no longer being updated in com.google.gdt.eclipse.core.prefs. We have a cross platform team and this prefs file is actually being shared between workspaces, but it used to function that this file would be updated whenever dev mode was run, it is no longer being updated and I have ended up with an invalid file path for linux due to it being committed by a windows user and the plugin creating the lastWarOutDir everytime it runs.

If this value is no longer being used, I would suggest that in the latest versions of the plugin it should be ignored, directory should not be created, it should not be updated.

Super trivial annoyance at this point.

I have removed the value from my local copy of the file to stop the directory from being created.

首先跟踪处理 com.google.gdt.eclipse.core.prefs 和 lastWarOutDir 值的 dev mode 路径。确定该值是否仍在使用，然后验证其在共享 Windows 和 Linux 工作区中的行为。完成的标准是该首选项不再导致创建无效目录，或者在仍然需要时能够正确更新。
