Gradle Goodness: Set Java Compiler Encoding

If we want to set an explicit encoding for the Java compiler in Gradle we can use the options.encoding property. For example we could add the following line to our Gradle build file to change the encoding for the compileJava task:

apply plugin: 'java'
compileJava.options.encoding = 'UTF-8'

To set the encoding property on all compile tasks in our project we can use the withType() method on the TaskContainer to find all tasks of type Compile. Then we can set the encoding in the configuration closure:

apply plugin: 'java'

tasks.withType(Compile) {
    options.encoding = 'UTF-8'
}
