How to configure the order of libraries in the classpath for Android Studio?

I use the following task to make sure that the SDK dependency is listed last:

task pushDownJdkDependency {    def imlFile = file("ui.iml")    doLast {        try {            def parsedXml = (new XmlParser()).parse(imlFile)            def jdkNode = parsedXml.component[1].orderEntry.find { it.'@type' == 'jdk' }            parsedXml.component[1].remove(jdkNode)            new Node(parsedXml.component[1], 'orderEntry', ['type': 'jdk', 'jdkName': "Android API 18 Platform", 'jdkType': 'Android SDK'])            def writer = new StringWriter()            new XmlNodePrinter(new PrintWriter(writer)).print(parsedXml)            imlFile.text = writer.toString()        } catch (FileNotFoundException e) {            // nop, iml not found        }    }}

make sure you use the correct SDK identifier. Then hook the task into the build process:

gradle.projectsEvaluated {    preBuild.dependsOn(pushDownJdkDependency)}

Other than that, add the task to your run configuration. Unfortunately I cannot post images due to lack of reputation.

You have to modify the project .iml file to have the JDK as the last entry like the following:

    <orderEntry type="library"                 exported=""                 scope="TEST"                 name="wagon-provider-api-1.0-beta-6"                 level="project" />    <orderEntry type="library"                 exported=""                 scope="TEST"                 name="xercesMinimal-1.9.6.2"                 level="project" />    <!-- make sure this is the last orderEntry -->    <orderEntry type="jdk"                 jdkName="Android API 19 Platform"                 jdkType="Android SDK" />   </component></module>
