Maven offers a nice script to allow for attaching a debugger to your build, mvnDebug. Gradle does not. Again, though, Gradle makes it pretty easy to add this to your build.

Let’s say you want to debug your tests:
build.gradle
test {
if (System.getProperty('DEBUG', 'false') == 'true') {
jvmArgs '-Xdebug',
'-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=9009'
}
}From the command line, issue gradle -DDEBUG=true test:
$ gradle -DDEBUG=true test
:compileJava UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE
:compileTestJava
:processTestResources UP-TO-DATE
:testClasses
:test
Listening for transport dt_socket at address: 9009
> Building > :testWhen you see that line, you can attach the debugger of your choice, using port 9009. This also works if you’re building a command line application:
build.gradle
run {
if (System.getProperty('DEBUG', 'false') == 'true') {
jvmArgs '-Xdebug',
'-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=9009'
}
}and run:
gradle -DDEBUG=true run
:compileJava UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE
:run
Listening for transport dt_socket at address: 9009
> Building > :runTo add this all of your projects, you can make this change to init.gradle:
~/.gradle/init.gradle
allprojects {
tasks.withType(Test) {
if (System.getProperty('DEBUG', 'false') == 'true') {
jvmArgs '-Xdebug',
'-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=9009'
}
}
tasks.withType(JavaExec) {
if (System.getProperty('DEBUG', 'false') == 'true') {
jvmArgs '-Xdebug',
'-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=9009'
}
}
}
