自动保存配置到properties文件中，比如对应版本号的递增，实现每次构建后版本不同

mysave.gradle

apply plugin:MySavePlugin


class MySavePlugin implements Plugin<Project>{

    @Override
    void apply(Project project) {
        def file=project.rootProject.file("myprop.properties")
        project.extensions.create("myprop",InnerStorage,file)
    }
}

class InnerStorage {

    Properties myProp
    File pFile;
    InnerStorage(File file){
        pFile=file;
        loadProperty()
    }

    private loadProperty(){
        myProp = new Properties()
        if(!pFile.exists()){
            pFile.createNewFile()
        }else {
            pFile.withInputStream {
                ins -> myProp.load(ins)
            }
        }
        println("loadProperty from $pFile --> $myProp")
    }

    def propertyMissing(String name, value) {
        myProp.setProperty(name,String.valueOf(value))
        save()
    }

    def propertyMissing(String name) {
        def v=myProp.getProperty(name)
        v.integer?v.toInteger():v.toString()
    }

    private save(){
        if(!pFile.exists()){
            pFile.createNewFile()
        }
        pFile.withOutputStream {
            os -> myProp.store(os,null)
        }
    }
}

mysave.md

在其他build.gradle 中

apply from: 'mysave.gradle'

task testSave(){
	println(project.myprop.abc)

    project.myprop.abc2++

    println(project.myprop.abc2)

    project.myprop.abc3="lldof"
    project.myprop.abc=234234
}

每次修改即可自动保存到myprop.properties文件中
