Gradle task does not execute its dependency

I'm trying to use http://launch4j.sourceforge.net/ through this Gradle plugin https://github.com/TheBoegl/gradle-launch4j.

When I do gradle clean launch4j I get the following output.

:clean
:compileJava
:processResources UP-TO-DATE
:classes
:jar
:copyL4jLib
:generateXmlConfig
:createExeWithBin SKIPPED
:unzipL4jBin
:copyL4jBinLib
:createExeWithJar FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':createExeWithJar'.
> meta-tagger.exe not created:
        launch4j: Icon doesn't exist.

I do not understand why copyResources is not run. Clearly :copyL4jLib is executed. Shouldn't Gradle figure out that copyResources comes before it and execute it first?

Here is my gradle -version info.

Gradle 2.10

And here is my build script.

plugins {
    id 'edu.sc.seis.launch4j' version '1.6.1'
    id 'java'
}

repositories {
    mavenLocal()
    mavenCentral()
    jcenter()
}

sourceCompatibility = JavaVersion.VERSION_1_8
targetCompatibility = JavaVersion.VERSION_1_8

task copyResources(type: Copy) {
    from 'src/main/wrapper-resources/'
    into 'build/launch4j'
}

copyL4jLib {
    dependsOn copyResources
}

launch4j {
    mainClassName = 'com.mpinnegar.Main'
    icon = 'favicon.ico'
    headerType = 'console'
    errTitle = 'Image Tagger'
    stayAlive = true
}

tasks.copyL4jLib.dependsOn copyResources
Solution

  • It seems the plugin is doing something weired. First it creates the task (see https://github.com/TheBoegl/gradle-launch4j/blob/develop/src/main/groovy/edu/sc/seis/launch4j/Launch4jPlugin.groovy#L50) and then replaces the task in an afterEvaluate block (see https://github.com/TheBoegl/gradle-launch4j/blob/develop/src/main/groovy/edu/sc/seis/launch4j/Launch4jPlugin.groovy#L122)

    To workaround this issue you should be able to put your task dependency setup in a afterEvaluate block to ensure you're configuring the replaced task:

    afterEvaluate {
    copyL4jLib.dependsOn copyResources    
}
