Re: [gradle-user] Conditional Task Dependency

[Rene Groeschke]

Hello Neil, a dependsOn declaration in a doFirst closure has no effect, because the doFirst closure is executed, when the task graph is already created and gradle executes each task in that directed graph. try ------------------- bar{   def aFile = file("/path/to/file")   if (!aFile.exists()) {     println "Doesn't exist"     dependsOn foo   } }   ------------------- instead. BTW.: the gradle forum (http://forums.gradle.org/gradle) is a much better place for this kind of question. regards, René Neil Chaudhuri 10. April 2012 19:23 I would like for one task to be dependent on another conditionally. The way I have tried this is as follows: task foo {   //Do stuff } task bar << {   //do other stuff } bar.doFirst {   def aFile = file("/path/to/file")   if (!aFile.exists()) {     println "Doesn't exist"     dependsOn foo   } } Unfortunately, even though executing bar produces the "Doesn't exist" statement, foo doesn't execute before  bar. It doesn't execute at all. Any insight into how I can enable conditional task dependencies is appreciated. Thanks.
