有什么想法吗？

Answer 1

你应该删除

1) ...\workspace.metadata.plugins\org.eclipse.e4.workbench"

告诉我状态。

2) 在每个工作空间内的 .metadata 目录中都有一个 .log 文件，该文件通常包含来自 Eclipse 内部的许多堆栈跟踪。启动崩溃通常在这里找到。我假设您已将 Eclipse 配置为在特定工作区中自动启动，而不提示您在启动时选择一个。

3) 在 eclipse.ini 中添加：

-vm C:/Program Files/Java/jdk1.8.0_5/jre/bin/javaw.exe 它可以工作。我将 JRE 更改为 JDK/JRE。

JAVA_HOME 和 JRE_HOME 应该指向上面的位置。

一一尝试这些方法。其中一种会奏效。这就像一个疑难解答。
