Eclipse 颠覆性；与修订版比较；在日食开普勒中总是失败

当我尝试将Eclipse开普勒中的当前文件与旧版本进行比较时，我总是得到 没有差异的消息（不正确），然后错误报告屏幕显示：

> SVN: '0x00400103: Compare with Revision' operation finished with
> error: null java.lang.NullPointerException

实际上，我从Subclipse切换到Subversive，因为比较在那里要高级得多，但是在将eclipse从计算机上迁移到另一台之后（这需要将我的项目重新链接到那里的repos），我不能再使用Compare了

.metadata/.logs

中的部分说明：

这似乎是Eclipse bug，在第三方SVN代码中作为bug关闭：

这可能是工作区

.metadata

目录中

.log

文件中更详细的消息。看到这一点可能会有所帮助。@greg-449添加的日志现在看起来很有希望。在EclipseKepler中找不到如何用1.8.2替换我的旧SVN工具包的说明。尝试从1.8.2更新站点简单安装，但重新启动后使用的SVN Kit连接器仍为1.8.1。
