Common Config (in progress)

apply plugin: 'java'

// specify Java version
sourceCompatibility = 1.8
targetCompatibility = 1.8

 
// for gradle run
mainClassName = "com.lidenlab.App"

}

Create runnable Jar file

Configure the Jar task of the Java plugin:

apply plugin: 'java'
 
jar {
    manifest {
        attributes 'Main-Class': 'com.lidenlab.App'
    }
}

apply plugin: 'java'

jar {

manifest {

attributes 'Main-Class': 'com.lidenlab.App'

}

Force running subsequent tests

# use the rerun flag
gradle test --rerun-tasks

# clean the tests
gradle cleanTest test

# configure test to depend on cleanTest in build.gradle
test {
    dependsOn 'cleanTest'
    //Your previous task details (if any)
}

# use the rerun flag

gradle test --rerun-tasks

# clean the tests

gradle cleanTest test

# configure test to depend on cleanTest in build.gradle

test {

dependsOn 'cleanTest'

//Your previous task details (if any)

}

Show StandardStreams from tests

// show System.out.println and System.err.println

test {
    testLogging {
        showStandardStreams = true
 
        // events method:
        // events 'STANDARD_OUT', 'STANDARD_ERROR'

        // events method with enum values:
        // events org.gradle.api.tasks.testing.logging.TestLogEvent.STANDARD_OUT,
        //        org.gradle.api.tasks.testing.logging.TestLogEvent.STANDARD_ERROR,
 
        // Or set events property:
        // events = ['STANDARD_OUT', 'STANDARD_ERROR']
    }
}

// show System.out.println and System.err.println

test {
