Hi all,
I used gradle 3.5 and gradle:2.2.0 plugin to compile my android project. I found that compileDebugJavaWithJavac task delete all the class file last compiled and rebuild again although config option incremental was true and only one file changed.
Below is my environment:
Win7, JDK1.8, Gradle3.5, gradle plugin 2.2.0
build.gradle
android{
compileOptions.incremental = true
}
afterEvaluate {
tasks.withType(JavaCompile) {
options.incremental = true // one flag, and things will get MUCH faster
options.fork = true
}
}
The log:
