How can I set the compileOptions for my Gradle Java plugin?
提问by Jazzepi
I want to set the -parameters command on my gradle build so that I can use reflection to access the name of the parameters. It seems like I should be doing this with the following closure.
我想在我的 gradle 构建中设置 -parameters 命令，以便我可以使用反射来访问参数的名称。似乎我应该使用以下闭包来做到这一点。
compileJava {
compileOptions {
compilerArgs << '-parameters'
}
}
But compileOptions is listed as read-only, and when I look at the source code there's no setter.
但是 compileOptions 被列为只读，当我查看源代码时，没有设置器。
How am I suppose to be able to tell the javac compiler what args to use in Gradle?
我怎么能告诉 javac 编译器在 Gradle 中使用什么参数？

Please try:
请试试：
apply plugin: 'java'
compileJava {
options.compilerArgs << '-parameters'
}

tasks.withType(JavaCompile) {
configure(options) {
options.compilerArgs << '-Xlint:deprecation' << '-Xlint:unchecked' // examples
}
}

You cannot overwrite all of the options (since 'options' property is read-only), but you can set them one by one. For example:
您不能覆盖所有选项（因为 'options' 属性是只读的），但您可以一一设置它们。例如：
compileJava {
//enable compilation in a separate daemon process
options.fork = true
//enable incremental compilation
options.incremental = true
}

You can work with Compile Options in App.gradlefile like this:
您可以在App.gradle文件中使用编译选项，如下所示：
android {
compileSdkVersion 28
buildToolsVersion "28.0.2"
defaultConfig {
applicationId "com.example.aliazaz.menuapp"
minSdkVersion 21
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
/*Add Compile options in following block*/
compileOptions {
//Like these
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
