如何让自己的jar包优先参与编译

buildscript {
    repositories {
        jcenter()
        google()

        gradle.projectsEvaluated {

            tasks.withType(JavaCompile) {
                //getOptions().compilerArgs.add('-Xbootclasspath/p:tools/tools-Lib-Smartisan/libs/backup.jar')
                getOptions().compilerArgs.add('-Xbootclasspath/p:libs/OverrideAndroidSDK.jar')
                //options.compilerArgs.add('-Xbootclasspath/p:tools/tools-Lib-Smartisan/libs/backup.jar')
            }
        }
    }
    // 引用jar不要放在这里，要放在
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.1'
    }
}
