Eclipse无法创建新的Java项目。

Question

Eclipse无法创建新的Java项目。

javalinuxeclipseopensuse

10

我正在openSUSE Tumbleweed上运行Eclipse 4.5.2（Mars）。不幸的是，当我点击新建->Java项目时，什么都没有发生，因此我无法创建Java项目...

我已经重新安装了Eclipse，清除了元数据，并从我的主目录中删除了用户数据。但是没有任何作用。

在我的日志中，我只得到以下错误信息： name= unhandled event loop exception; plugin= org.eclipse.ui;

你没有说明在哪个桌面环境下运行 Eclipse（KDE、GNOME、LXDE），不过 Eclipse 似乎与新的 GTK3 不太兼容。

我通过强制让 Eclipse 使用 GTK2 来解决了这个问题，你可以在 eclipse.ini 文件中添加以下两行：

--launcher.GTK_version
2

请确保在--launcher.appendVmargs行上方添加这两行。
