Gradle常用的幾十個(gè)命令一網(wǎng)打盡!
?安卓進(jìn)階漲薪訓(xùn)練營(yíng)
，讓一部分人先進(jìn)大廠
大家好，我是皇叔，最近開(kāi)了一個(gè)安卓進(jìn)階漲薪訓(xùn)練營(yíng)，可以幫助大家突破技術(shù)&職場(chǎng)瓶頸，從而度過(guò)難關(guān)，進(jìn)入心儀的公司。

前言
Gradle的命令有很多，熟悉常用命令之后，在日常開(kāi)發(fā)中，不僅可以提升效率，也可以輔助我們快速定位并解決編譯問(wèn)題；而且某些情況下命令行(CLI)與按鈕執(zhí)行的編譯結(jié)果是不一樣的，比如構(gòu)建時(shí)要傳參(-P)，所以就單拎出來(lái)一篇講解，希望對(duì)你有幫助~
1.Gradle命令
1.1、gradlew
Gradle執(zhí)行命令行主要用到的是Gradle Wrapper，關(guān)于Gradle Wrapper的介紹，在前文( 【Gradle-2】一文搞懂Gradle配置 )中有介紹，這里不再贅述。https://juejin.cn/post/7160337743552675847#heading-5
所以我們常用的 ./gradlew (Mac)，gradlew即Gradle Wrapper的簡(jiǎn)寫。
Gradle Wrapper工作流：
再來(lái)看下gradlew的腳本內(nèi)容：

代碼量不多，gradlew主要干了幾件事：
-
獲取電腦系統(tǒng)內(nèi)核的信息，JRE環(huán)境信息等；
-
設(shè)置classpath路徑；
-
執(zhí)行java命令工具，調(diào)用gradle jar包的class文件；
1.2、命令大全

簡(jiǎn)寫：
./gradlew -？
//?or
./gradlew?-h
可以看到上面的輸出已經(jīng)列出來(lái)了很多命令，可能有些見(jiàn)過(guò)有些沒(méi)見(jiàn)過(guò)，下面將把常用的提煉出來(lái)講解，并進(jìn)行分類。
1.3、命令結(jié)構(gòu)
gradle?[taskName...]?[--option-name...]
多個(gè)任務(wù)用空格分隔。
2.Gradle相關(guān)
2.1、查看Gradle版本
常見(jiàn)的查看Gradle版本有兩種方式。
第一種是直接在gradle>wrapper> gradle-wrapper.properties 文件下查看 distributionUrl 所使用的gradle版本下載地址：
distributionUrl=https://services.gradle.org/distributions/gradle-7.4-bin.zip
這里的 distributionUrl 即表示當(dāng)前所用的gradle版本為7.4。
第二種就是使用命令行的方式查看當(dāng)前版本。
執(zhí)行：
?./gradlew?-version
//?or
./gradlew?-v
輸出：
------------------------------------------------------------
Gradle?7.4
------------------------------------------------------------
Build?time:???2022-02-08?09:58:38?UTC
Revision:?????f0d9291c04b90b59445041eaa75b2ee744162586
Kotlin:???????1.5.31
Groovy:???????3.0.9
Ant:??????????Apache?Ant(TM)?version?1.10.11?compiled?on?July?10?2021
JVM:??????????11?(Oracle?Corporation?11+28)
OS:???????????Mac?OS?X?10.16?x86_64
2.2、升級(jí)Gradle
常見(jiàn)的升級(jí)Gradle有3種方式。
第一種，先手動(dòng)修改 wrapper.properties 文件下 distributionUrl 指向的版本，再手動(dòng)修改Android Gradle Plugin(AGP)版本，然后重新sync。
第二種，打開(kāi)file>Project Structure修改AGP和Gradle的版本，然后apply。
第三種，用命令行的方式(官方推薦，不過(guò)跟著AS一起升也是可以的)：
./gradlew?wrapper?--gradle-version?7.5.1
3.編譯命令
3.1、檢查依賴并編譯打包
./gradlew?build
3.2、編譯并打出Debug包
./gradlew?assembleDebug
3.3、編譯打出Debug包并安裝
./gradlew?installDebug
3.4、編譯并打出Release包
./gradlew?assembleRelease
3.5、編譯打出Release包并安裝
./gradlew?installRelease
3.6、Debug/Release編譯并打印日志
./gradlew?assembleDebug?--info
//?or
./gradlew?assembleRelease?--info
4.清除命令
清除構(gòu)建目錄下的產(chǎn)物。
./gradlew?clean
等同于Build->Clean Project。
5.卸載命令
5.1、卸載Debug/Release安裝包
./gradlew?uninstallDebug
//?or
./gradlew?uninstallRelease
輸出：
Uninstalling?com.yechaoa.gradlex?(from?app:debug)?from?device?'Pixel_5_API_31(AVD)?-?12'?(emulator-5554).
Uninstalled?com.yechaoa.gradlex?from?1?device.
5.2、adb卸載
在Android Studio中執(zhí)行是直接卸載的當(dāng)前項(xiàng)目安裝包，如果是adb執(zhí)行則需要指定包名。
adb?uninstall?com.yechaoa.gradlex??
6.調(diào)試命令
調(diào)試命令在定位編譯問(wèn)題的時(shí)候非常有用。當(dāng)我們遇到編譯錯(cuò)誤的時(shí)候，經(jīng)常會(huì)看到這個(gè)提示：
*?Try:
>?Run?gradle?tasks?to?get?a?list?of?available?tasks.
>?Run?with?--stacktrace?option?to?get?the?stack?trace.
>?Run?with?--info?or?--debug?option?to?get?more?log?output.
>?Run?with?--scan?to?get?full?insights.
6.1、編譯并打印堆棧日志
./gradlew?assembleDebug?--stacktrace
//?or
./gradlew?assembleDebug?-s
詳細(xì)版：
./gradlew?assembleDebug?--full-stacktrace
//?or
./gradlew?assembleDebug?-S
6.2、日志級(jí)別
有時(shí)候構(gòu)建日志會(huì)有很多，看到的可能不全，甚至不是真正的編譯問(wèn)題，而構(gòu)建日志又不能像logcat那樣可以可視化的篩選，這個(gè)時(shí)候就需要用日志級(jí)別來(lái)篩選一下。
-q，--quiet
僅記錄錯(cuò)誤。
-w，--warn
將日志級(jí)別設(shè)置為警告。
-i，--info
將日志級(jí)別設(shè)置為信息。
-d，--debug
調(diào)試模式（包括正常的stacktrace）。
示例：
./gradlew?assembleDebug?-w
7.任務(wù)相關(guān)
7.1、查看主要Task
./gradlew?tasks
7.2、查看所有Task
./gradlew?tasks?--all
7.3、執(zhí)行Task
./gradlew?taskName
//?or
./gradlew?:moduleName:taskName
同時(shí)，可在AS右側(cè)工具類Gradle中查看項(xiàng)目及module的Task，并可以點(diǎn)擊執(zhí)行對(duì)應(yīng)Task。
8.查看依賴
編譯有很多問(wèn)題都是依賴導(dǎo)致的錯(cuò)誤，查看依賴能幫我們快速定位問(wèn)題所在。
8.1、查看項(xiàng)目根目錄下的依賴
./gradlew?dependencies
8.2、查看app模塊下的依賴
./gradlew?app:dependencies
8.3、查看依賴輸出到文件
./gradlew?app:dependencies?>?dependencies.txt
示例：
9.性能相關(guān)
9.1、離線編譯
./gradlew?assembleDebug?--offline
9.2、構(gòu)建緩存
./gradlew?assembleDebug?--build-cache?//?開(kāi)啟
./gradlew?assembleDebug?--no-build-cache?//?不開(kāi)啟
9.3、配置緩存
./gradlew?assembleDebug?--configuration-cache?//?開(kāi)啟
./gradlew?assembleDebug?--no-configuration-cache?//?不開(kāi)啟
9.4、并行構(gòu)建
./gradlew?assembleDebug?--parallel?//?開(kāi)啟
./gradlew?assembleDebug?--no-parallel?//?不開(kāi)啟
以上9.1-9.4的配置也都可以在 gradle.properties 中配置。
示例：
#并行編譯
org.gradle.parallel=true
#構(gòu)建緩存
org.gradle.caching=true
9.5、編譯并輸出性能報(bào)告
./gradlew?assembleDebug?--profile
性能報(bào)告位于構(gòu)建項(xiàng)目的GradleX/build/reports/profile/路徑下。
See?the?profiling?report?at:?file:///Users/yechao/AndroidStudioProjects/GradleX/build/reports/profile/profile-2022-11-29-23-13-29.html
輸出的是html文件，用瀏覽器打開(kāi)：
9.6、編譯并輸出更詳細(xì)性能報(bào)告
./gradlew?assembleDebug?--scan
首次執(zhí)行需要郵箱驗(yàn)證，授權(quán)即可，完事之后即可打開(kāi)鏈接，scan報(bào)告內(nèi)容比profile更加詳細(xì)。
10.動(dòng)態(tài)傳參
再來(lái)介紹一個(gè)比較常用的傳參屬性， --project-prop ，我們一般常用-P表示，用來(lái)設(shè)置根項(xiàng)目的項(xiàng)目屬性。
10.1、獲取參數(shù)
示例：
?./gradlew?assembleDebug?-PisTest=true?
這里我們用-P傳了一個(gè)isTest字段，并賦值為true。
那在代碼里如何獲取這個(gè)參數(shù)呢？然后在 build.gradle 中編寫如下代碼：
if?(hasProperty("isTest")){
????println("---hasProperty?isTest?yes")
}else?{
????println("---hasProperty?isTest?no")
}
我們可以用 hasProperty 來(lái)獲取命令行(CLI)的參數(shù)，module或者插件也可以這么獲取：
project.property('isTest')
然后我們用上面的命令編譯看下輸出：
???GradleX?git:(master)???./gradlew?assembleDebug?-PisTest=true?
---Gradle：開(kāi)始初始化了
---Gradle：settingsEvaluated Settings對(duì)象評(píng)估完畢
---Gradle：projectsLoaded 準(zhǔn)備加載Project對(duì)象了
>?Configure?project?:
---Gradle：Projec beforeEvaluate Project開(kāi)始評(píng)估，對(duì)象是?= GradleX
---hasProperty?isTest?yes?//???---?看這里?---
---Gradle：Projec afterEvaluate Project評(píng)估完畢，對(duì)象是?= GradleX
>?Configure?project?:app
---Gradle：buildFinished 構(gòu)建結(jié)束了
可以看到已經(jīng)打印出來(lái)了。
還沒(méi)完，獲取到參數(shù)是不錯(cuò)，但是還沒(méi)獲取到參數(shù)的值。
10.2、獲取參數(shù)值
我們可以用 getProperty() 來(lái)獲?。?/span>
if?(hasProperty("isTest"))?{
????println("---hasProperty?isTest?yes")
????if?(Boolean.valueOf(getProperty('isTest')))?{
????????println("---isTest?true")
????}?else?{
????????println("---isTest?false")
????}
}?else?{
????println("---hasProperty?isTest?no")
}
注意， getProperty('isTest') 這里要用單引號(hào)，另外命令行里面的參數(shù)值都是對(duì)象，還需要基本數(shù)據(jù)類型轉(zhuǎn)換一下，即 Boolean.valueOf(getProperty('isTest')) 。
10.3、自定義操作
ok，現(xiàn)在我們就可以針對(duì)獲取的參數(shù)去做一些自定義的操作了，比如修改我們的依賴。
app> build.gradle ：
dependencies?{
????implementation?'androidx.core:core-ktx:1.7.0'
????if?(project.hasProperty("isTest"))?{
????????println("---hasProperty?isTest?yes")
????????if?(Boolean.valueOf(getProperty('isTest')))?{
????????????println("---isTest?true")
????????????implementation?'com.yechaoa.gradlex.devtools:devtools:1.1.1'
????????}?else?{

這里舉例，在 isTest=true 的時(shí)候依賴了devtools 1.1.1版本， isTest=false 時(shí)依賴了devtools 2.2.2版本。
除了 dependencies 里面的依賴之外，Plugin、Task之類的也可以通過(guò)動(dòng)態(tài)傳參的方式去做自定義操作。11.總結(jié)
本文介紹了Gradle Command-Line Interface(CLI)相關(guān)的知識(shí)，像調(diào)試命令、查看依賴、性能相關(guān)、動(dòng)態(tài)傳參這些，在定位問(wèn)題、提升效率的時(shí)候還是非常有用的，希望能給你帶來(lái)收獲。（別忘了三連啊喂~）
