tomcat - Grails 编译错误 - "package does not exist"

Question

我是 grails 的新手，正在通过使用 helloWorld-Controller 设置一个简单的应用程序来跟踪。在执行 create-app 并打开交互式控制台后，我遇到了以下问题。

grails> create-controller projects | Compiling 10 source files. | Error Compilation error: startup failed: Compile error during compilation with javac. C:\dev\grails-2.3.5\timespent\target\work\plugins\tomcat-7.0.50\src\java\org\grails\plugins\tomcat\TomcatKillSwitch.java:3: error: package org.apache.catalina does not exist

我尝试了 grails clean 和 grails refresh-dependencies compile 但错误仍然出现。

完整的堆栈跟踪继续了一点，但似乎没有什么重要的。

我的系统上有不止一个 tomcat，但据我所知，grails 使用的是捆绑的 tomcat。

谁能说出 javac 失败的原因？毕竟，这是一个全新的安装，除了加载依赖项之外，它并没有做太多事情。

问题解决了，看我上面的评论

add the tomcat as external jar in the eclipse project build path and delete the "target" folder in the project
