Gradle Properties
Project Properties Debugging
Want to see at runtime which properties were passed to your project. You can use the following script to print properties in following order.
- Gradle extra properties
- All Gradle properties
- Arguments to Gradle JVM
- All system properties
import java.lang.management.RuntimeMXBean
import java.lang.management.ManagementFactory
println("==== START EXT Gradle Properties ====")
project.properties.ext.properties.forEach{key, value ->
println("KEY: $key, VALUE is: $value")
}
println("==== START Gradle Properties ====")
project.properties.forEach{key, value ->
println("KEY: $key, VALUE is: $value")
}
println("==== START Gradle JVM Arguments ====")
RuntimeMXBean runtimeMXBean = ManagementFactory.getRuntimeMXBean()
List<String> jvmArgs = runtimeMXBean.getInputArguments()
for (String arg : jvmArgs) {
System.out.println(arg)
}
println("==== START System Properties ====")
System.getenv()
System.getProperties().forEach{key, value ->
println("KEY: $key, VALUE is: $value")
}
Be aware this can print many properties containing that with sensitive information.
Unfortunately you won’t be able to get access to all command line arguments that were passed with Gradle CLI from the IDE, except if they were passed as project or system properties.
Example resutl when running following command gradlew testTask -i -PprojectProperty=projectProperty -DsystemProperty=systemProperty'
