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

Maven needs to be able to access various Maven repositories in order to download artifacts to the local repository. If your local system is accessing the Internet through a proxy host, you might need to explicitly specify the proxy settings for Maven by editing the Maven settings.xml file. Maven builds ignore the IDE proxy settings that are set in the Options window. For many common cases, just passing -Djava.net.useSystemProxies=true to Maven should suffice to download artifacts through the system's configured proxy. NetBeans 7.1 will offer to configure this flag for you if it detects a possible proxy problem. https://netbeans.org/bugzilla/show_bug.cgi?id=194916 has discussion.

Answer 2

Had the same problem, I worked around it by changing ${java.home}/../bin/javafxpackager to ${java.home}/bin/javafxpackager

Answer 3

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.

Answer 4

Netbeans needs to be able to index the maven repository. Allow it to do that and try again. It was giving me the same error and after it indexed the repository it ran like a charm

Answer 5

Restart Netbeans & it solved my problem.

Answer 6

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
