无法在Tomcat上部署Grails应用程序6

Question

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

这个异常在一分钟后抛出。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复它。 ： -/

Answer 1

您应该将commons-pool-1.4.jar添加到您的应用程序runtime范围内。
添加

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

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