Add task dependency to existing Gradle task
提问by Giovanni Botta
I'm going to lose my mind about this. I have a build.gradlefile that looks something like:
我会失去理智的。我有一个build.gradle看起来像这样的文件：
apply plugin: 'idea'
task blah{
// do something
}
idea{
// some stuff
dependsOn blah
}
and I'm getting this:
我得到了这个：
Could not find method dependsOn() for arguments [task ':blah'] on root project ...
I can't figure out what the right syntax is. Any help?
我无法弄清楚正确的语法是什么。有什么帮助吗？

This should work:
这应该有效：
apply plugin: 'idea'
task blah{
// do something
}
tasks.idea.dependsOn(blah)

Maybe my working example would be useful - fragments of build.gradle: (gradle version's 1.6)
也许我的工作示例会很有用 - build.gradle 的片段：（gradle 版本的 1.6）
ear {
doFirst {
tasks.buildWar.execute();
}
...
}
task deployProj <<{
tasks.ear.execute()
tasks.copyEar.execute()
tasks.copyJar.execute()
}
task buildWar(type: GradleBuild) {
buildFile = 'mysubproject/build.gradle'
tasks = ['war']
}
task copyEar(type: Copy) {
from earPath
into "$System.env.JBOSS_HOME" + deploymentPath
}
task copyJar(type: Copy) {
from jarPath
into libPath
}
copyEar.mustRunAfter 'ear'
copyJar.mustRunAfter 'ear'

I had a very similar error:
我有一个非常相似的错误：
Could not find method runEC2Step1DownloadSource() for arguments [{dependsOn=task ':docker:buildCopyEC2BuildFiles'}, task ':docker:runEC2SetupVariables', build_cwq7epb31twoanyxdhq1zosc7$_run_closure16@2a0fe301] on project ':docker' of type org.gradle.api.Project.
My problem was that my task runEC2Step1DownloadSourcewas defined like this:
我的问题是我的任务runEC2Step1DownloadSource是这样定义的：
task runEC2Step0CreateMachine(dependsOn: buildCopyEC2BuildFiles, runEC2SetupVariables) {
doLast {
// A bunch of stuff
}
}
And the solution was to add an ARRAY to the list of dependsOn tasks:
解决方案是在dependsOn任务列表中添加一个ARRAY：
task runEC2Step0CreateMachine(dependsOn: [buildCopyEC2BuildFiles, runEC2SetupVariables]) {
doLast {
// A bunch of stuff
}
}
Note the extra [] brackets around the list of dependsOn tasks.
请注意dependsOn 任务列表周围的额外[] 括号。
