eclipse - "Error while loading manipulator"

Question

尝试安装 WTP 网页编辑器插件时，我在 Eclipse Galileo 下不断收到以下错误:

java.lang.IllegalStateException: Error while loading manipulator.

一个博客说 Eclipse Galileo 不能很好地与 Java 1.6 配合使用(什么？？)，因此我尝试使用 Java 1.5 运行 Eclipse，但这没有帮助。还有其他人遇到过这个问题并且能够解决它吗？

编辑顺便说一句，错误日志中的错误下方还显示了

session 上下文为:(profile=epp.package.java, Phase=org.eclipse.equinox.internal.provisional.p2.engine.phases.Install, operand=null --> [R]javax.邮件 1.4.0.v200905040518，action=org.eclipse.equinox.internal.p2.touchpoint.eclipse.actions.InstallBundleAction)。

您可以尝试遵循bug 277242中提到的各种建议。

另请检查您的 eclipse.ini:

More generally, the error you're seeing can happen when we cannot read "-startup" since we use this to position the install.area.

根据Jelle van Geuns的建议在评论中(并由 Halfstop 确认):

I found that one MacOS there are two folders (MacOS and Eclipse) with two separate sets of configuration files.
Each had an 'org.eclipse.equinox.launcher' startup jar in the plugins sub-folder, but with slightly different versions.

The Eclipse executable resides in the MacOS folder.
But the eclipse.ini there was set up to look for the startup jar under Eclipse/plugins, but with the wrong version.

Solution that worked for me was to copy both versions of the startup.jar to both the plugins sub-folders.

Halfstop确认:

I copied all of the what was in Eclipse to the MacOS directory and this solved it.
