Maven won't run my Project : Failed to execute

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) on project 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.

Answer 1

For me, the clue was the "org.codehaus.mojo:exec-maven-plugin:1.2.1:exec".
The only place this was referenced was in the "Run project" action under Project Properties=>Actions.

When I changed this action to match the HelloFXMLWithMaven sample project (available in Netbeans 11.1): "clean javafx:run" then executing the Run goal was able to proceed.

Note, I also had to update the pom file's javafx-maven-plugin to also match the sample project but with the mainClass changed for my project.

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.

Im new to java hibernate but i could solve this problem, this is how i did it : I was working with hibernate and maven project. First you have to put persistence.xml under project directory, then add jdbc manually. Maven couldn't download my dependency so i added it manually. In the persistence.xml in design jdbc connection add it manually ps: i work with netbeans good luck

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.

Answer 5

I solved this issue with right click on project -> Set as Main Project.

Answer 6

Had the same problem after installing oracle jdk on Ubuntu 13.10 x64.

I've done the following steps, not sure which one helped. I think that at least 2 and 3 are necessary.

1. Deleted Netbeans 7.4 and reinstalled it from oracle's site.
2. Installed plugins for maven, ant and java that may be related to the project.
3. Deleted .nbproject folder - after that the project was considered a maven project.

Also, after that, I've found that the project runs, but exits with exit code 1 because I didn't supply the command line parameters for it. And the builder considers it is an error. So, look carefully for the output and see if the program actually starts.
