Gradle SubProject任务未处理

问题描述

我为具有以下结构的Java项目设置了多模块。

mainApp
|--> core-module
|       |--> src
|       |--> build.gradle
|       |--> gradle.properties
|       
|--> lib-module
|       |--> src
|       |--> build.gradle
|       |--> gradle.properties
|--> lib-another-module
|       |--> src
|       |--> build.gradle
|       |--> gradle.properties
|--> settings.gradle
|--> build.gradle

在我提到的mainApp/build.gradle中

subprojects {
    test.dependsOn "CreateMessageKeys"
    //test.dependsOn ":CreateMessageKeys"
    //test.dependsOn ("CreateMessageKeys")
    //test.dependsOn (":CreateMessageKeys") none of this working....

}

task CreateMessageKeys(type: CreateMessageKeysTask) {
    destDir = "bundle-common/src/";
    outputClass = "common.messages.MessageKeys";
}

和我的core-module/build.gradle的测试目标为

test {
    useTestNG() { 
        useDefaultListeners = true
        suites 'test/testng.xml' 
    }
}

但出现如下错误。.我在这里想念什么？

Caused by: groovy.lang.MissingMethodException: No signature of method: java.lang.String.dependsOn() is applicable for argument types: (String) values: [CreateMessageKeys]
Possible solutions: respondsTo(java.lang.String)

修改

subprojects {
    test.dependsOn(rootProject.tasks['CreateMessageKeys'])
}

task CreateMessageKeys(type: CreateMessageKeysTask) {
    destDir = "bundle-common/src/";
    outputClass = "common.messages.MessageKeys";
}

它会产生错误：

* What went wrong:
A problem occurred evaluating root project 'myApp'.
> Task with name 'CreateMessageKeys' not found in root project 'mainApp'.

解决方法

任务定义看起来不正确，请参见defining tasks。

它应该像这样：

task ('CreateMessageKeys',type: CreateMessageKeysTask) {
    destDir = "bundle-common/src/";
    outputClass = "common.messages.MessageKeys";
}

或

task (CreateMessageKeys,type: CreateMessageKeysTask) {
    destDir = "bundle-common/src/";
    outputClass = "common.messages.MessageKeys";
}

对这个问题的反对：

在第二个示例中，当评估任务CreateMessageKeys时可能还不存在。一种可能的解决方法如下：

subprojects.each {
    it.afterEvaluate {
         it.test.dependsOn(...)
    }
}

或者只是将任务定义放在此块上方可以解决此问题。
