gradle wrapper --gradle-version [version]
compile command
Check dependencies and compile and package
./gradlew build
Compile and export the Debug package
./gradlew assembleDebug
Compile and print the Debug package and install it
./gradlew installDebug
Compile and export the Release package
./gradlew assembleRelease
Compile and print the Release package and install it
./gradlew installRelease
Debug/Release compiles and prints logs
./gradlew assembleDebug --info
./gradlew assembleRelease --info
Clear the products in the build directory
./gradlew clean
Uninstall Debug/Release installation package
./gradlew uninstallDebug
./gradlew uninstallRelease
output:
Uninstalling com.yechaoa.gradlex (from app:debug) from device 'Pixel_5_API_31(AVD) - 12' (emulator-5554).
Uninstalled com.yechaoa.gradlex from 1 device.
adb uninstall
is executed in Android Studio to directly uninstall the current project installation package. If it is executed by adb, you need to specify the package name.
adb uninstall packagename

Compile and output performance report
./gradlew assembleDebug --profile
The performance report is located in the GradleX/build/reports/profile/ path of the built project.
See the profiling report at: file:///Users/yechao/AndroidStudioProjects/GradleX/build/reports/profile/profile-2022-11-29-23-13-29.html
Compile and output a more detailed performance report
./gradlew assembleDebug --scan
The first execution requires email verification, authorization is sufficient, and the link can be opened after completion. The content of the scan report is more detailed than that of the profile.
Dynamic parameter passing
The more commonly used parameter passing attribute, –project-prop, we generally use -P to indicate that it is used to set the project properties of the root project
Get parameters
./gradlew assembleDebug -PisTest=true
Here we use -P to pass an isTest field and assign it to true.
So how to get this parameter in the code? Then write the following code in build.gradle:
if (hasProperty("isTest")){
println("---hasProperty isTest yes")
}else {
println("---hasProperty isTest no")
}
We can use hasProperty to obtain the parameters of the command line (CLI), and the module or plug-in can also be obtained in this way:
project.property('isTest')
Then we use the above command to compile and see the output:
➜ GradleX git:(master) ✗ ./gradlew assembleDebug -PisTest=true
---Gradle：开始初始化了
---Gradle：settingsEvaluated Settings对象评估完毕
---Gradle：projectsLoaded 准备加载Project对象了
> Configure project :
---Gradle：Projec beforeEvaluate Project开始评估，对象是 = GradleX
---hasProperty isTest yes // --- 看这里 ---
---Gradle：Projec afterEvaluate Project评估完毕，对象是 = GradleX
> Configure project :app
---Gradle：buildFinished 构建结束了
get parameter value
We can use getProperty() to get:
if (hasProperty("isTest")) {
println("---hasProperty isTest yes")
if (Boolean.valueOf(getProperty('isTest'))) {
println("---isTest true")
} else {
println("---isTest false")
}
} else {
println("---hasProperty isTest no")
}
Note that getProperty('isTest') uses single quotes here, and the parameter values in the command line are all objects, and the basic data type needs to be converted, that is, Boolean.valueOf(getProperty('isTest')).
custom action
We can do some custom operations on the obtained parameters, such as modifying our dependencies.
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 {
println("---isTest false")
implementation 'com.yechaoa.gradlex.devtools:devtools:2.2.2'
}
} else {
println("---hasProperty isTest no")
}
testImplementation 'junit:junit:4.13.2'
}
at last
If you want to become an architect or want to break through the 20-30K salary range, then don't be limited to coding and business, but you must be able to select models, expand, and improve programming thinking. In addition, a good career plan is also very important, and the habit of learning is very important, but the most important thing is to be able to persevere. Any plan that cannot be implemented consistently is empty talk.
If you have no direction, here I would like to share with you a set of "Advanced Notes on the Eight Major Modules of Android" written by the senior architect of Ali, to help you organize the messy, scattered and fragmented knowledge systematically, so that you can systematically and efficiently Master the various knowledge points of Android development.
Compared with the fragmented content we usually read, the knowledge points of this note are more systematic, easier to understand and remember, and are arranged strictly according to the knowledge system.
