java - Eclipse RCP应用程序仅以管理员身份启动

Question

几天前，我们决定在Eclipse RCP应用程序中开始使用Guava。我从http://central.maven.org/maven2/com/google/guava/guava/14.0.1/下载guava-14.0.1.jar。

启动eclipse.exe之后，应用程序崩溃了。 .metadata/.log文件包含以下错误:

如果应用程序以管理员身份运行，则没有错误。

该应用程序是64位的，因此这不是UAC虚拟化问题。但是看起来问题出在某种程度上与权限有关。

guava-14.0.1.jar似乎是有效的OSGi软件包:https://code.google.com/p/guava-libraries/issues/detail?id=688(至少我在MANIFEST.MF中找到了所有必要的 header )

有什么建议？

我通过清除C:\Users\<user_name>\.eclipse文件夹解决了我的问题。看来问题出在某种程度上与OSGi(Equinox)临时目录有关。
