Eclipse Spring Boot Build Path Contains Duplicate Entry
提问by skmansfield
I have been using Eclipse Luna and sprint boot for quite a while. Just today, when I created a new project I am getting the following build error,
我使用 Eclipse Luna 和 sprint boot 已经有一段时间了。就在今天，当我创建一个新项目时，我收到以下构建错误，
Build path contains duplicate entry: 'org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8' for project 'TomcatHttpDemo'
I am not sure if this is related to this problem but I tried
我不确定这是否与这个问题有关，但我试过了
properties> Java Build Path > Libraries
and found that 'JRE System Library[JavaSE-1.8] was listed twice. I deleted one of them and then cleaned and re-built the project. I got a bunch of new errors. These errors were all related to deleting the JRE system library. I even restarted Eclipse several times to clear out any lingering errors.
并发现'JRE System Library[JavaSE-1.8]被列出了两次。我删除了其中之一，然后清理并重新构建了该项目。我遇到了一堆新错误。这些错误都与删除JRE系统库有关。我什至多次重新启动 Eclipse 以清除任何挥之不去的错误。
I was running Luna 4.4 and upgraded to Mars 4.5 but the problem continues to persist. I can build my old projects with no problems at all. Using Luna or Mars the old projects build and execute properly. Any time I try to create a new project I get the duplicate entry error. Any help would be appreciated.
我正在运行 Luna 4.4 并升级到 Mars 4.5，但问题仍然存在。我可以毫无问题地构建我的旧项目。使用 Luna 或 Mars 可以正确构建和执行旧项目。每当我尝试创建一个新项目时，都会出现重复输入错误。任何帮助，将不胜感激。
