执行Java类时发生异常。 java.lang.InterruptedException

Question

I get my Apache Storm from http://mirror.symnds.com/software/Apache/storm/apache-storm-0.9.3/apache-storm-0.9.3.tar.gz

I never modified any thing in the /home/user/storm/examples/storm-starter/ directory.

When I run this command

mvn exec:java -D storm.topology=storm.starter.WordCountTopology

in the /home/user/storm/examples/storm-starter/, it gives the error as below:

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:java (default-cli) on project storm-starter: An exception occured while executing the Java class. java.lang.InterruptedException -> [Help 1]
[ERROR] 
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
[ERROR] 
[ERROR] For more information about the errors and possible solutions, please read the following articles:
[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException

Anyone know what is the problem & how to solve it? I wish can provide me a detail solution as I am a newbie. Thank you.

Try this

Go to the path where your pom.xml file exists and run this command

mvn -e -f pom.xml compile exec:java -D storm.topology=storm.starter.WordCountTopology

Try adding this to your pom.xml and run the above command.

    <artifactId>exec-maven-plugin</artifactId>
    <version>1.2.1</version>
