无法在 Tomcat 6 上部署 Grails 应用程序

Question

我无法在我的 Tomcat 6 上部署我的 Grails 2.2.4 应用程序。我尝试过全新安装 tomcat 甚至是我的应用程序的旧版本（之前运行过）。

一分钟后抛出此异常。 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复它。 :-/

Answer 1

您应该使用runtime 范围将commons-pool-1.4.jar 添加到您的应用程序中。
添加

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

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