eclipse - STS 中 Grails 的类路径容器

Question

我在 Grails 依赖项上遇到 STS 问题。有一个条目指向错误的目录。内部 STS 构建因错误而失败:

Problems occurred when invoking code from plug-in: "org.eclipse.core.resources".

Grails 命令 run-app 工作正常。

我通过将插件类链接到

来获取此条目

C:\Documents and Settings\<myUserName>\.grails\1.3.7\projects\<ProjectName>\plugin-classes

现在我正在寻找一种方法来删除此条目，但在“项目”->“构建路径”->“配置构建路径”->“库”下，删除按钮被禁用。

如果我查看 .classpath 文件，我会看到以下条目:

<classpathentry kind="con" path="org.grails.ide.eclipse.core.CLASSPATH_CONTAINER"/>

Google 关于 CLASSPATH_CONTAINER 的信息未成功。conf 目录中的文件没有变化(与 subversion 不同)

我已经尝试过这样做:

1. 删除 .ivy2 文件夹
2. 删除 .grails 文件夹
3. 干净的 chalice
4. Grails-> 刷新依赖项
5. 项目 -> 清理
6. 删除项目并从 SVN 导入最新版本
7. 删除工作区并创建新的工作区
8. 1..7 的任意组合

请帮忙!

Answer 1

1. 删除 .ivy2 文件夹
2. 删除 .grails 文件夹
3. 删除 .m2 文件夹
4. 从 application.properties 中删除所有添加的插件
5. 从 BuildConfig.groovy 中删除所有添加的插件
6. 尝试重新启动您的项目 - 现在应该可以工作
7. 重新安装插件
