Maven项目将无法运行

Question

this is my first attempt in making a maven project. Usually I just create regular Java projects, but this time I need to use Firebase so I had to resort to maven dependencies. For testing purposes the application only establishes connection with Firebase and get a reference to the project's real time database. The problem is my code won't even run, I'm using NetBeans on Windows 10 and when I try to run, the following message appear: Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec (default-cli) on project SEMS: Command execution failed. Process exited with an error: 1 (Exit value: 1) Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec (default-cli) on project SEMS: Command execution failed. Process exited with an error: 1 (Exit value: 1) . Thank you.

So far I have tried:

1. Deleting NetBeans Cache
2. Run mvn clean install

Here is my pom.xml :

Answer 1

Read the exception at the end of the build (eg: mvn -e install ):

Caused by: org.apache.maven.plugin.MojoExecutionException: The parameter 'executable' is missing or invalid

You are missing the executable parameter as described here: http://www.mojohaus.org/exec-maven-plugin/exec-mojo.html#executable

The pom.xml you are referencing in your question does not contains the plugin.

You should start with that:

• if you try to execute mvn org.codehaus.mojo:exec-maven-plugin:1.6.0:exec , then you'll need to pass the executable and other stuff using -Dexecutable=path/to/executable .
• if you try to execute it during the build, then you'll need appropriate plugin descriptor: http://www.mojohaus.org/exec-maven-plugin/examples/example-exec-for-java-programs.html
