1. 输出混淆了的 jar 包
1. build.gradle 脚本
- 生成 jar 包
def SDK_BASENAME = "raw_du";
def SDK_VERSION = "";
def sdkDestinationPath = "build";//生成jar存放目录
//打包release目录下的classes.jar(开启混淆后这个jar就是混淆的源码)----注意由于as版本原因有的在default目录
def releaseJar = file('build/intermediates/intermediate-jars/release/classes.jar')
//打包jar前先删除原先的jar
task deleteBuild(type: Delete) {
delete sdkDestinationPath + SDK_BASENAME + SDK_VERSION + ".jar"
}
task makeJar(type: Jar) {
from zipTree(releaseJar)//导出混淆的jar
//from zipTree(debugJar)//导出未混淆的jar
//from zipTree(thirdPartyJar)将第三方jar包打入jar包
//from fileTree(dir: 'src/main', includes: ['assets/**'])//将assets目录打入jar包
exclude('**/BuildConfig.class')//排除不必要的class文件
baseName = SDK_BASENAME + SDK_VERSION
destinationDir = file(sdkDestinationPath)
}
makeJar.dependsOn(deleteBuild, build)
上面这个就是生成了 jar 文件，对应 build/raw_du.jar 目录
- 生成混淆了的 jar 包
task makeProguardJar(type: proguard.gradle.ProGuardTask, dependsOn: ['makeJar']) {
// 未混淆的jar路径
injars 'build/raw_du.jar'
// 混淆后的jar输出路径
outjars 'build/proGuard_du.jar'
// 混淆协议
configuration 'proguard-rules.pro'
}
直接生成了 build/proGuard_du.jar 混淆后的文件
- 生成混淆了的 jar 包
task makePPPJar(type: proguard.gradle.ProGuardTask, dependsOn: "build") {
//删除已有的jar包
delete 'build/proGuard_du.jar'
// 未混淆的jar路径
injars 'build/intermediates/intermediate-jars/release/classes.jar'
// 混淆后的jar输出路径
outjars 'build/proGuard_du.jar'
// 混淆协议
configuration 'proguard-rules.pro'
}
这个 gradle 命令，对应的混淆配置是 proguard-rules.pro
模版如下
#表示混淆时不使用大小写混合类名
-dontusemixedcaseclassnames
#表示不跳过library中的非public的类
-dontskipnonpubliclibraryclasses
#打印混淆的详细信息
-verbose
# Optimization is turned off by default. Dex does not like code run
# through the ProGuard optimize and preverify steps (and performs some
# of these optimizations on its own).
-dontoptimize
##表示不进行校验,这个校验作用 在java平台上的
-dontpreverify
# Note that if you want to enable optimization, you cannot just
# include optimization flags in your own project configuration file;
# instead you will need to point to the
# "proguard-android-optimize.txt" file instead of this one from your
# project.properties file.
