Maven won't run my Project : Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec

Question

I can't run the Maven Netbeans JavaFX example :

Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec (default-cli) onproject mavenproject3:
  Command execution failed. Process exited with an error: 1 (Exit value: 1) -> [Help 1]

  To see the full stack trace of the errors, re-run Maven with the -e
  switch. Re-run Maven using the -X switch to enable full debug logging.

My POM looks like this :

    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Does anyone know why this is happening?

And if not, does anyone know how to get Maven running with the -e or the -X switch via Netbeans? I assume it is via a right click on the POM and then run goal then entering something in the textfield there.

1. This error would spring up arbitrarily and caused quite a bit of trouble though the code on my end was solid.

I did the following :

• I closed it on netbeans.
• Then open the project by clicking "Open Project", selecting my project and
• Simply hit the run button in netbeans.

I would not build or clean build it. Hope that helps you out.

2. I noticed another reason why this happens. If you moved your main class to another package, the same error springs up. In that case you :
   • Right Click Project > Properties > Run
   • Set the "Main Class" correctly by clicking "Browse" and selecting.

I faced the same issue. When I tried to run the project from IDE, it was giving me same error. But when I tried running from the command prompt, the project was running fine. So it came to me that there should be some issue with the settings that makes the program to Run from IDE.

I solved the problem by changing some Project settings. I traced the error and came to the following part in my pom.xml file.

            <execution>
                <id>default-cli</id>
                <goals>
                    <goal>exec</goal>                            
                </goals>
                <configuration>
                    <executable>${java.home}/bin/java</executable>
                    <commandlineArgs>${runfx.args}</commandlineArgs>
                </configuration>
            </execution>

I went to my Project Properties > Actions Categories > Action: Run Project: then I Set Properties for Run Project Action as follows:

runfx.args=-jar "${project.build.directory}/${project.build.finalName}.jar"

Then, I rebuild the project and I was able to Run the Project. As you can see, the IDE(Netbeans in my case), was not able to find 'runfx.args' which is set in Project Properties.

1. what's happening? you haven' shown much of the output to be able to decide. if you are using netbeans 7.4, try disabling Compile on Save.

2. to enable debug output, either run Custom > Goals... action from project popup or after running a regular build, click the Rerun with options action from the output's toolbar

Answer 4

I am a beginner in Maven - don't know much about it. Carefully check on your input i.e. file path in my case. After I have carefully check, my file path is wrong so it leads to this error. After I fixed it, it works magically lol.
