安装 Maven 插件并关闭 Eclipse 后，我尝试启动 Eclipse v8.3 我收到一个错误，将我指向配置目录的日志文件。（以下内容）即使在选择工作空间之前也会发生这种情况。
Root exception:
java.lang.IllegalStateException: MetadataRepositoryManager not registered.
at org.eclipse.equinox.internal.provisional.p2.directorywatcher.RepositoryListener.initializeMetadataRepository(RepositoryListener.java:115)
谷歌搜索 MetadataRepositoryManager 并没有出现太多......
重新启动后，互联网建议并且我已经尝试（并恢复）：
在 IBM\SDP\configuration\config.ini 中指定 eclipse.p2.data.area 的完整路径
在 IBM\SDP\configuration\config.ini 中将 eclipse.product=com.ibm.rational.rft.product.ide 更改为 eclipse.product=org.eclipse.platform.ide
重命名：C:\Users[用户名].eclipse
运行：\IBM\SDP>.\eclipse.exe –clean
在 \IBM\SDP\eclipse.ini 中将 JRE 从 1.7 更改为 1.6
删除工作区目录
删除配置目录（导致不同的问题：java 错误代码 = 13）
按照此处的建议删除 .snap 文件：http ://www.metod.si/job-found-still-running-after-platform-shutdown-eclipse/
这些更改（现已恢复）似乎都没有帮助。
提前感谢您可能添加的任何建议。
