'java.lang.AssertionError:assertion failed'启动Scala-IDE时出错(Eclipse)

Question

'java.lang.AssertionError:assertion failed'启动Scala-IDE时出错(Eclipse)

Hem*_*apu 6 java eclipse scala scala-ide

我是eclipse的新手.如果我对某事有误,请原谅.

我已经为eclipse 4.6.1下载了Scala IDE.我已经提取了内容并尝试启动eclipse.最初maven存在问题:' 无法读取maven-resources-plugin的工件描述符 '.通过将代理设置添加到.m2文件夹中的settings.xml,我能够解决此错误(我假设是因为它没有再次显示).

现在我收到一条新错误:' java.lang.AssertionError:assertion failed '

以下是完整错误:

我试着重新下载eclipse并重新启动.但我仍然得到同样的错误.

任何帮助,将不胜感激.谢谢.

我有类似的问题.我设法在不创建新工作区的情况下通过编辑打开eclipse:

工作区/ .metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi

并从中删除所有"persistedState"xml节点.

更新:

正如其他回应和评论所说.删除文件工作区/ .metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi似乎没有副作用.

在我的情况下它工作.删除文件也可以. (3认同)

删除

workspace/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi

Run Code Online (Sandbox Code Playgroud)

整体也有效.退出工作空间后会生成一个新的workbench.xmi.

我针对此崩溃的存储库案例是：使用 m2e 编辑器打开任何 POM。尽管我在首选项中选择了更喜欢 XMl，但 m2e 编辑器尝试以结构化视图（而不是 XML 模式）打开。结构化视图崩溃并在 eclipse 事件循环中创建了 eclipse NPE 的无限循环。人们必须关闭窗户并再次打开。然后 XML 视图打开。只要您打开了 POM（现在处于 XML 模式），此工作区的任何重新启动都会触发此崩溃。解决方法（对我来说）是在重新启动 Eclipse 之前关闭所有 POM 编辑器。
