安裝Maven插件並關閉Eclipse之後，我嘗試啓動Eclipse v8.3。我收到一個錯誤，指向配置目錄的日誌文件。 （下面的內容）甚至在選擇工作空間之前，會發生這種情況安裝Maven插件後，Eclipse不再啓動：MetadataRepositoryManager未註冊
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不轉了多少......
重啓後，互聯網已經建議，我已經試過（和恢復）：
指定完整路徑蝕。 IBM \ SDP \ configuration \ config.ini中的p2.data.area
將eclipse.product = com.ibm.rational.rft.product.ide更改爲eclipse.product = org.eclipse.platform.ide in IBM \ SDP \ configuration \ config.ini
重命名：C：\用戶[用戶名] .eclipse
運行：\ IBM \ SDP> \的eclipse.exe -clean
在\ IBM \ SDP \蝕從1.7改變JRE至1.6。 INI
卸下工作區目錄
卸下配置目錄（導致不同的問題：Java錯誤代碼= 13）
卸下.snap文件作爲這裏提出：http://www.metod.si/job-found-still-running-after-platform-shutdown-eclipse/
這些更改（現在還原）似乎都沒有幫助。
非常感謝您提供的任何建議。
