Maven Embedded 3.3.9 - Is it possible?

Question

So I am trying to embed maven in my code rather than use a shell wrapper however I am having issues getting it to actually work.

Source Code

The master branch works however it is an older version of maven (3.1.1) and I would like to use a more recent version.

The 339 branch has every dependency that I can pin down for that version defined in pom.xml.

However no amount of playing with the dependencies will help avoid the following error.

java -jar maven-embedder-example-1-jar-with-dependencies.jar package
[main] WARN Sisu - Error injecting: org.apache.maven.project.DefaultProjectBuildingHelper
com.google.inject.ProvisionException: Unable to provision, see the following errors:

I have gone through every SO question I can find and read lots of mailing lists but it seems like very few people want to do this or I am just failing.

Do you fine folks have any idea?

I am running this inside of an in house automation system and want to avoid using a process wrapper. — xandout, Apr 07 '17 at 04:07
What is the problem? Why not simply calling maven as usual from command line which works ...The question is what kind of problem are you trying to solve? — khmarbaise, Apr 07 '17 at 09:18
Because the environments this will run in do not have a maven installation. If I can get this to work then it solves a lot of issues with distribution. — xandout, Apr 07 '17 at 11:38

I've just hit the same problem as you. I hope it's not too late for a solution.

The problem you got is related to use maven-embedder inside a shade/fatjat/jarwithdependencies

When you create the jar-with-dependencies, some resources may be defined in many jars but only one is packed inside the jar (the last one processed). Here is where the problem lays with the META-INF/plexus/components.xml and META-INF/sisu/javax.inject.Named files required by Maven and Plexus

The fix this problem you should:

Exclude all this files when building the jar-with-dependencies
Create this files in your project as the concatenations of the files contained in you dependencies.

In my case, I use maven-shade-plugin to build the jar-with-dependecies. So to exclude the files from the dependency jars is done this way:

            <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>

        </plugin>

This way only the META-INF/plexus/components.xml and META-INF/sisu/javax.inject.Named created in your project are included in the fatjar

I had the same issue. However I was using Spring Boot, so was able to use the repackage goal of the spring-boot-maven-plugin to build my fat jar, rather than the maven-assembly-plugin or the maven-shade-plugin.

  <build>
    <plugins>
      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <configuration>    
          <mainClass>com.acme.test.Application</mainClass>
        </configuration>
        <executions>
          <execution>
            <goals>
              <goal>repackage</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
