我是Linux新手（一般情况下，但Mint专门），但是能够让eclipse打开（Java版本openjdk版本“9-internal”），运行Eclipse Oxygen1.A。 （我不得不最后编辑eclipse.ini，如其他一些帖子所述，以启动应用程序（例如：删除-add ALL MODULES等）
程序现在开始正常，但在创建项目时遇到以下错误:(见下文）
我尝试过创建新的工作区，没有任何运气。我正在尝试创建一个Java9项目，但也尝试创建Java8项目，仅用于测量..
有任何建议或建议吗？
提前感谢任何/所有建议。 （PS：可能值得一提的是我的核心体验是在Windows中，我已经在Windows 10操作系统中配置了新的Oxygen / Java9，以便按预期运行..）

答案 0 :(得分：1)
固定！ 当使用Oomph安装程序用于Eclipse时，需要指向新安装的JDK9.0.1 ....无论出于何种原因，存在/默认的“openJDK 9-Interal”无效...... 如果有其他人在Mint上设置eclipse的类似问题，我建议从java.com上获取干净/新鲜的JDK，并仔细配置Oomph安装程序（确保两者都是64位），并将其指向此JDK而不是默认..
