grails - 使用Weceem插件在Grails中创建可部署的 war

Question

我将GGTS 3.6.4与Grails 2.4.5，Weceem 1.3和Java 1.8u40一起使用。
我使用weceem插件在Grails中创建了一个Web应用程序，当我使用grails run-app命令启动该应用程序时，一切正常。

我试图通过该项目创建可部署的 war ，但是每次安装 war 时，只会显示一个空白的页面。 war 甚至不包含index.html等。

然后，我尝试创建一个新的Grails项目，其中包括weceem 1.3插件并执行命令grails run war。结果是一样的。我只显示了一个空白页。当我使用run-app命令时，一切正常。

这似乎是核心问题:

failed to create task or type componentdef

如果您使用自己喜欢的搜索引擎在Google上搜索到该图片，则会经常看到在war文件中同时包含Ant 1.7.x和1.8.x jar的原因。 Grails 2.4.5使用Ant 1.8.4，但是Ant jar的作用范围不包括在 war 中-您是否在BuildConfig.groovy中添加了显式依赖项？

我的猜测是Weceem或它依赖的插件之一具有Ant 1.7依赖关系。如果这是问题所在，则一旦确定哪个插件导致包含Ant，您应该能够为Ant 1.7添加排除对象。或者，您可以使用 grails.war.resources从登台目录中删除多余的jar，然后再将所有文件添加到war中。这在docs和 this Marc Palmer blog post中进行了描述，就像

grails.war.resources = { stagingDir ->
    delete(file:"$stagingDir/WEB-INF/lib/ant-1.7.???.jar")
}
