No plugin found for prefix 'exec' in the current project and in the plug in groups org.codehaus.mojo

exec-maven-plugin

I have read several questions with similar issue and the Help 1 page. Unfortunately, I am stuck.

One possible reason could be caused by proxy but there is no such proxy here. Additionally, all maven projects in my PC have been successfully updated when I update it from Eclipse. So I discard this possibility.

Other thing I checked was to look for codehaus in my local repository and I find it (C:\Users\myUser.m2\repository\org\codehaus\mojo).

Another try, I tried add pluginGroups/pluginGroup in settings. The project is a very simple hello word using spring batch with only a Tasklet and its execute method. There isn't public static void main method.

Command.exe with the whole error printed after I added the Matteo recommendation:

C:\temp\TaskletJavaConfig\spring-batch-helloworld>mvn compile exec:java -e

You should configure your pom file to at least declare the Exec Maven Plugin as following:

<build>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>exec-maven-plugin</artifactId>
            <version>1.1</version>
        </plugin>
    </plugins>
</build>

As such, you will be able to use the exec:java plugin:goal command.

You can even avoid the options:

-Dexec.mainClass=org.springframework.batch.core.launch.support.CommandLineJobRunner -Dexec.args="com.test.config.HelloWorldJobConfig helloWorldJob"

By configuring them in your POM as part of the same plugin configuration as following:

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.1</version>
    <configuration>
        <mainClass>org.springframework.batch.core.launch.support.CommandLineJobRunner</mainClass>
        <arguments>
            <argument>com.test.config.HelloWorldJobConfig</argument>
            <argument>helloWorldJob</argument>
        </arguments>
    </configuration>
</plugin>

As you can see, we are actually saying to the plugin where to find the main class and its arguments. You could then hence simply invoke:

mvn compile exec:java

And it should perform the same expected results.

Update1
Indeed, your maven execution is having troubles to access the plugin metadata on the network:

[WARNING] Failed to retrieve plugin descriptor for org.codehaus.mojo:exec-maven- plugin:1.1: Plugin org.codehaus.mojo:exec-maven-plugin:1.1 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.codehaus .mojo:exec-maven-plugin:jar:1.1

Update2
If you keep on having issues with the plugin prefix, then indeed it might depend on your network settings. A quick check could be performed by invoking the Exec Maven Plugin not via its plugin prefix (exec) but via full qualified name as following:

mvn compile mvn org.codehaus.mojo:exec-maven-plugin:1.1:java

Note the pattern: we are invoking maven, then a groupId:artifactId:version:goal, it will be exactly the same. That will check whether your pom configuration (and plugin configuration) is correct or not.

Update3
As seen in your output log, Maven is trying to access repositories via https (note the final 's'), hence via SSL and then having issues with certificates as part of the build output:

sun .security.validator.ValidatorException: PKIX path building failed: sun.security. provider.certpath.SunCertPathBuilderException: unable to find valid certificatio n path to requested target

You have two options then:

  • Tell maven to ignore SSL errors, as described in another SO answer
  • Check your settings firstly via running mvn help:effective-settings to make sure you get the real settings applied by maven (if the command will work actually), then re-configuring non SSL repositories in your settings with the alternative on another SO answer
