"在Grails 2.3数据库迁移中加载插件管理器:TomcatGrailsPlugin时出错"

Question

我使用Grails 2.3和Grails数据库迁移插件(1.3.6).

当我做grails dbm-update时,我收到以下错误.我该如何解决这个错误？

Answer 1

这是一个非常讨厌的 bug.我的应用程序依赖于使用run-script运行脚本,我得到了相同的行为.这是我做的解决方法:

plugins {
    ...
    // grails 2.3.2 and tomcat 7.0.42 cause scripts to not work :( Pass -DnoTomcat=true in the script args to fix this
    if (System.getProperty("noTomcat") == null) {
        build ":tomcat:7.0.42"
    }
}

然后在运行脚本时:

 grails -DnoTomcat=true run-script scripts/MyScript.groovy

当然很烦人,但至少你可以在等待修复时使用所有其他最新功能.

Answer 2

尝试更改buildConfig.groovy中的tomcat构建类型以编译而不是构建:

compile ':tomcat:7.0.42'
