Java Gradle:任务依赖关系树被忽略？

我对gradle的任务依赖性有问题

我有一个version.properties文件，必须用版本信息清除（在清理任务中）或填充（在war任务中）

因此，我设置了此依赖项：

clean.dependsOn clearVersionProperties

及

我的任务已在commons.gradle中外部化，如下所示：

...

def writeVersionFile(String whatToWrite) {
    File f = new File(project.webAppDirName+'/WEB-INF/version.properties');
    if (f.exists()) { f.delete(); }

    f = new File(project.webAppDirName+'/WEB-INF/version.properties');
    FileOutputStream os = new FileOutputStream(f);
    os.write(whatToWrite.getBytes());
    os.flush();
    os.close();
}

task clearVersionProperties() {
    println "Clearing version file"
    String whatToWrite = "version=@version@"
    writeVersionFile(whatToWrite)
}

task writeVersionProperties(dependsOn: svnRevision) {
    println "Writing version file"
    String whatToWrite = "version="+project.ext.revision;
    writeVersionFile(whatToWrite)
}
...

据我所知，clean现在将调用clearVersionProperties，而war将调用writeVersionProperties

但当我执行梯度清洁时，反应堆计划如下所示：

C:\devtools\....\branches\merge\Application>gradle -bbuild20.gradle clean -Ptomcat=7 -Ptarget=live

为什么要执行clearVersionProperties和writeVersionProperties任务，因为它们绑定到特定的构建阶段？例如，任务infoEnv没有执行，但是任务writeVersionProperties只应该由war任务执行，这确实是一个问题

感谢您的帮助

与此同时，我发现了这些任务被解雇的原因：

我错过了这就是为什么你不应该使用

，但是，如果我想使用增量构建，除了
doLast
之外，我没有其他选择了（我不确定你在这里如何与增量构建建立联系），我只想在gradle clean上清除属性文件，只想在gradle war上写入属性，最好是在文件不存在的情况下。这将是一个渐进的步骤，对吗？
