无法在Tomcat 6上部署Grails应用程序

Question

我无法在Tomcat 6上部署Grails 2.2.4应用程序。我尝试了新安装的tomcat，甚至我的应用程序的旧版本（以前运行过）。

此异常在一分钟后引发。在tomcat启动后：

The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact.

我真的不知道从哪里开始修理它-/

Answer 1

您应该添加commons-pool-1.4。jar提供给具有运行时范围的应用程序
添加

grails.project.dependency.resolution = {
   // ...  
   dependencies {
        // ...
        runtime 'commons-pool:commons-pool:1.4'
   }
   // ...
}  

到项目文件grails-app/conf/BuildConfig。groovy
