执行packageReleaseJar后,自动将versionCode增加1

Question

我在build.gradle的android标签中有以下内容以增加versionCode:

apply plugin: 'com.android.library'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    def versionPropsFile = file('version.properties')

    if (versionPropsFile.canRead()) {
        def Properties versionProps = new Properties()

        versionProps.load(new FileInputStream(versionPropsFile))
        List<String> runTasks = gradle.startParameter.getTaskNames();
        def value = 0
        for (String item : runTasks)
            if (item.contains("packageReleaseJar")) {
                value = 1;
            }

        def code = versionProps['VERSION_CODE'].toInteger() + value
        versionProps['VERSION_CODE'] = code.toString()
        versionProps.store(versionPropsFile.newWriter(), null)

        defaultConfig {
            minSdkVersion 8
            targetSdkVersion 22
            versionCode code
            versionName version
            testApplicationId 'se.android.instrumenttest'
            testInstrumentationRunner 'se.android.Runner'

            printf("\n--------" + "VERSION DATA--------"
                    + "\n" + "- CODE: " + versionCode + "\n" +
                    "- NAME: " + versionName + "\n----------------------------\n")
        }

    } else {
        throw new GradleException("Could not read version.properties!")
    } 

这个想法取自commonsguy样本.

我希望当我packageReleaseJar使用Gradle包装器执行任务时,versionCode增加1.但它没有按预期工作.

我想这可能与generateReleaseBuildConfig任务有关.

可能是什么原因以及解决方案是什么？

附加物

def getVersionCode() {
    def versionPropsFile = file('version.properties')
    if (versionPropsFile.canRead()) {
        def Properties versionProps = new Properties()
        versionProps.load(new FileInputStream(versionPropsFile))
        def code = versionProps['VERSION_CODE'].toInteger()

    } else {
        throw new GradleException("Could not read version.properties!")
    }
    return code
}

这个方法没有按预期工作,但是当在android标签中使用方法的逻辑时,问题将会解决:

def versionPropsFile = file('version.properties')
    if (versionPropsFile.canRead()) {
        def Properties versionProps = new Properties()
        versionProps.load(new FileInputStream(versionPropsFile))
        def code = versionProps['VERSION_CODE'].toInteger()

        defaultConfig {
            minSdkVersion 8
            targetSdkVersion 22
            versionCode code
            versionName version
            testApplicationId 'se.android.instrumenttest'
            testInstrumentationRunner 'se.android.Runner'

            printf("\n--------" + "VERSION DATA--------\n" +
                    "- CODE: " + versionCode + "\n" +
                    "- NAME: " + versionName +
                    "\n----------------------------\n")
        }

    } else {
        throw new GradleException("Could not read version.properties!")
    }
