Groovy 代码未突出显示

Question

我直接从 Eclipse 下载页面下载了 Eclipse - Eclipse IDE for Java EE Developers 并解压缩了它

但是，当我打开 .groovy 文件时，它没有突出显示。我尝试从this page下载并运行Groovy plugin

在安装过程中，eclipse 告诉我，groovy 已经安装好了：

但是代码仍然没有突出显示...您能告诉我接下来应该尝试哪些步骤来突出显示代码吗？

Answer 1

The most likely cause for this is that you are editing your groovy file in a Java editor.
