Running Gradle application with parameters in NetBeans

Question

I want to run Gradle application with my own parameter in NetBeans.

Example:

java - jar NameOfJarFile -MyParametere valueOfParameter

And what I must do to run my application with that parameter?

Answer 1

Although this is an old thread, it might be interesting to mention that I also had this problem using Netbeans and the Gradle plugin and I found 2 solutions, one of them a 'final' one.

• Solution 1: not final

  • I added the following line to my build.gradle file:

    cmdLineArgs = '-v -test'

    That seems to do the job.

    When I do a normal Run Main Project or Debug Main Project in NetBeans, all goes well. I get the two parameters as arguments to my main class.

    !!!However!!!: I get an error when I try to run a Clean and Build Main Project. The error is pointing to the cmdLineArgs line I added to my build.gradle file. This is the error message I get:

    A problem occurred evaluating root project 'PublicApiCheckerWithGradle'. Could not set unknown property 'cmdLineArgs' for root project 'PublicApiCheckerWithGradle' of type org.gradle.api.Project.

    I still don't know why this is...

    If someone has a better Gradle understanding than me and knows what causes this strange behaviour, I'm interested to know...

• Solution 2: final

  • Right-click on the NetBeans project, select Properties and then select Custom Variables in the Categories: section of the dialogue box that opens

  • Add the following line in the Custom Variables: section: cmd-line-args=-v -test

  • Close the dialogue box

    Now I can clean and rebuild, build and debug without any issues. The two arguments are always provided to my main method.

Hopefully it helps someone else too.

Best.

I realize this is an older thread, but I've just spent most of an afternoon trying to resolve this. Here's what I came up with after pulling parts of various solutions together.

1. In your build.gradle file, add the following:

tasks.named('run') {
    if ( project.hasProperty("cmdArgs") ) {
        args Eval.me(cmdArgs)
    }
}

2. Right click on the project and select Properties -> Configurations

3. Clone the default configuration (I named my new configuration default_cli)

Project Properties - Configurations

4. Edit your new configuration adding the command line parameters you want to pass to the application as an array called cmdArgs in Properties. In my case, I added cmdArgs=['-c','config.json']

Editing configuration settings

5. Activate your new configuration and run your application. You should now see the parameters in your main method args array:

Ninad's answer is not valid, since the question was for a Gradle project. For Gradle projects, the project properties dialog doesn't have those options. Instead it has:

Here is what the Project Properties dialog shows:

Unfortunately, this is a question I also have. I have attempted to add a Custom Task that supplies the arguments, but when I do, I get a gradle build error which is attempting to run my first argument as a gradle task. It doesn't seem possible to supply arguments in a NetBeans gradle project.

I tried a workaround by going to the command line and running: "gradle jar" to create a jar. Then I tried the standard method of running a jar: "java -jar jarname.jar arg1 arg2" and I get an error from java that:

no main manifest attribute, in jarName.jar

Right Click your project > properties > select Run in LHS panel > in Arguments textfield - enter parameters with spaces in between.
