Question

我的Eclipse运行缓慢，所以我决定卸载并重新安装它。似乎Eclipse只将文件安装到我的Users目录中，所以我只是为了卸载而删除它们。如果有一个更干净的卸载可以解决以下安装问题，那将是非常棒的。

所以重新安装时，我收到了一个错误。这是安装日志：

Answer 1

尝试删除以下文件并重新安装： C：\ Users \用户Cobal.p2 \ org.eclipse.equinox.p2.repository \缓存1747184149

Answer 2

我最终只是将其安装在另一个文件夹中。我想在我的Users目录中还有一些其他的eclipse文件，所以在另一个地方安装工作正常。不是一个正确的解决方案，但它确实有效。

Answer 3

如果您想彻底重新安装eclipse，可以删除用户目录C:\Users\Cobal\中以下文件夹的内容：

.eclipse
.p2
.tooling

请注意，其他eclipse实例可以使用这些文件夹。如果您的电脑上安装了多个eclipse，请小心删除这些文件夹，进行备份。
