如何在使用Android Gradle Plugin进行编译时添加java编译器选项?
我有一个带依赖项的
和 build.gradle
文件{classpath'com.android.tools.build:grad:0.13.3'} 申请插件:'com.android.application'
。
I have a build.gradle
file with dependencies { classpath 'com.android.tools.build:gradle:0.13.3'}
and apply plugin: 'com.android.application'
.
当我这样做时调试构建我得到:
When I do a debug build I get:
gradle clean assembleDebug
:myapp:preBuild
(...)
:myapp:compileDebugJava
Note: C:\path\to\MyClass.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
:myapp:preDexDebug
(...)
:myapp:assembleDebug
BUILD SUCCESSFUL
如何将 -Xlint:unchecked
添加到基础任务? 有关Java编译选项的Gradle插件用户指南是无益的。
How can I add the -Xlint:unchecked
to the underlying task? Gradle Plugin User Guide on Java compilation options is unhelpful.
我找到了基于 Gradle Plugin操作任务用户指南和 Gradle关于JavaCompile的DSL文档:
添加到 build.gradle
:
preBuild {
doFirst {
JavaCompile jc = android.applicationVariants.find { it.name == 'debug' }.javaCompile
jc.options.compilerArgs = ["-Xlint:unchecked"]
}
}
应用程序变体 null
在Gradle的配置阶段,所需的 JavaCompile
任务也不存在,因此我在执行阶段进行修改。
The application variants are null
during Gradle's configuration phase and the required JavaCompile
task also doesn't exist, thus I do the modification in the execution phase instead.
