gradle - 如何强制Gradle在每个版本上运行任务？

Question

我在Mac Yosemite上使用Gradle 2.7。在构建WAR时，假设所有测试都通过并且 war 的组装成功了，我想将WAR复制到本地$CATALINA_HOME/wbeapps目录中。所以我在build.gradle脚本中定义了这个:

task deployToTomcat(type: Copy) {
    from war.archivePath
    into "$System.env.CATALINA_HOME/webapps"
}

build.dependsOn deployToTomcat

当我运行 gradle build时，我可以看到该任务已运行，但是在 $CATALINA_HOME/webapps目录中什么也没有显示。这是输出:

davea$ gradle build
:compileJava UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE
:war UP-TO-DATE
:assemble UP-TO-DATE
:compileTestJava UP-TO-DATE
:processTestResources UP-TO-DATE
:update

:testClasses
:test UP-TO-DATE
:check UP-TO-DATE
:deployToTomcat UP-TO-DATE
:build UP-TO-DATE

“UP-TO-DATE”是否已运行？如何强制任务运行？

编辑:根据给出的答案，我更改了任务。 WAR文件将复制到与我的“build.gradle”文件相同的目录中的名为“null / webapps”的文件夹。这是输出

davea$ echo $CATALINA_HOME
/opt/apache-tomcat-6.0.44
davea$ gradle build
:compileJava UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE
:war UP-TO-DATE
:deployToTomcat UP-TO-DATE
:assemble UP-TO-DATE
:compileTestJava UP-TO-DATE
:processTestResources UP-TO-DATE

无需强制执行任务。相反，请适当配置任务:

task deployToTomcat(type: Copy) {
    from war.outputs
    into "$System.env.CATALINA_HOME/webapps"
}

war.finalizedBy deployToTomcat

archivePath定义了放置 war 的路径，但是要获得 war ，您需要使用任务的 outputs属性。
finalizedBy总是在完成任务后运行给定任务。在这种特殊情况下，这保证了将要准备构建的 Artifact 。
UP-TO-DATE表示该任务未运行。没关系
