How do I package source and documentation jars separately on deploy? - maven

I notice that most distributions package their artifacts like
my-1.0.jar
my-1.0-sources.jar
my-1.0-documentation.jar
when I do a deploy I currently only get the my-1.0.jar how do I get the sources and documentation generated as separate jars?

I added maven-source-plugin and maven-javadoc-plugin to the build.plugins section of my parent pom.xml. Worth saying that I originally accidentally put them in pluginManagement and of course that would only work if I manually included them in the child.
<build>
<plugins>
<plugin>
<artifactId>maven-source-plugin</artifactId>
<executions>
<execution>
<id>attach-sources</id>
<goals>
<goal>jar</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<artifactId>maven-javadoc-plugin</artifactId>
<executions>
<execution>
<id>attach-javadocs</id>
<goals>
<goal>jar</goal>
</goals>
</execution>
</executions>

Goal copy-dependencies in maven-dependency-plugin is not executed

I have the following plugin configuration :
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>3.2.0</version>
<configuration>
<outputDirectory>${project.build.directory}/alternateLocation</outputDirectory>
</configuration>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
</execution>
</executions>
</plugin>
When calling mvn dependency:copy-dependencies dependencies are indeed copied, and at the correct location (alternateLocation). But when I'm calling mvn package nothing is performed. What am I missing ?
As per documentation, you need to have your configuration inside the execution.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>3.2.0</version>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<!-- configure the plugin here -->
</configuration>
</execution>
</executions>
</plugin>
We only see parts of your POM, but I guess you put the plugin into <pluginManagement> and not into <plugins> where it belongs.

Get the semantic versioning components within a Maven POM [duplicate]

Is it possible to get the major version (<Major>.<Minor>.<Patch>) of the project.version?
For example if my version is 1.3.4, I'd like to get 1 to later use it in a configuration of the same pom.xml
Something like:
<configuration>
<name>project_name.${project.version:major}</name>
</configuration>
If not, what are the alternatives?
Found it. The build-helper-maven-plugin has the ability to parse-out the components of the version.
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>1.5</version>
<executions>
<execution>
<phase>initialize</phase>
<id>parse-version</id>
<goals>
<goal>parse-version</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.1</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<tasks>
<echo>[version] ${project.version}</echo>
<echo>[majorVersion] ${parsedVersion.majorVersion}</echo>
</tasks>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
This works on Maven 3.3.9:
${project.artifact.selectedVersion.majorVersion}
Versions don't necessarily come in the structure you describe.
Maven has conventions for trailing numbers, but you don't have to use them.
If you have a convention that you like that you want to disassemble, you can write your own maven plugin that sets several properties to the several pieces as you define them.

Source feature generated by Tycho is not being included in p2 repository

I'm trying to create and include a source feature of my plugins in the generated p2 repository. Currently, the source jars for each plugin get created, as does the source feature to each normal feature. However, those source features then don't get included in the final product, an eclipse update site.
In my parent POM, I have
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-source-plugin</artifactId>
<executions>
<execution>
<id>plugin-source</id>
<goals>
<goal>plugin-source</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.eclipse.tycho.extras</groupId>
<artifactId>tycho-source-feature-plugin</artifactId>
<version>${tycho.version}</version>
<executions>
<execution>
<id>source-feature</id>
<phase>package</phase>
<goals>
<goal>source-feature</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-p2-plugin</artifactId>
<version>${tycho.version}</version>
<executions>
<execution>
<id>attach-p2-metadata</id>
<phase>package</phase>
<goals>
<goal>p2-metadata</goal>
</goals>
</execution>
</executions>
</plugin>
Do I need to add something to the POM of the feature? Of the eclipse-repository? I'm out of ideas.
Gonna answer this myself. I found a solution thanks to this article.
I had to add the generated source feature to the category.xml that describes my update site.
I had tried that before but it didn't work because I made the mistake of writing *.source.feature instead of *.feature.source.

using maven dependency (:copy) plug in not working

I can't seem to figure this out.
I have the following in my pom.xml
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>3.1.0</version>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>compile</phase>
<goals>
<goal>compile</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
<overWriteReleases>true</overWriteReleases>
<overWriteSnapshots>true</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
</executions>
</plugin>
I plan to have all the dependencies copied to target/lib directory.
Why is not doing it?
My project is evolving, so I do not want specify each individual artifact to copy. I want it to take them all, and place it into a proper place during the "package" (or compile) phase.
I get only my mainProject.jar file in the lib folder.
Please, help. What am I missing?
The correct goal for copying dependencies is copy-dependencies, not compile. Also, if you want to invoke the plugin from the command line with mvn dependency:copy, the configuration section should not be inside the executions. Here is a configuration that should work in all cases:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>3.1.0</version>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
</execution>
</executions>
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
<overWriteReleases>true</overWriteReleases>
<overWriteSnapshots>true</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</plugin>
As you can see, I'm running the plugin in the 'package' phase, but it also works in the 'compile' phase, unless you want to include the artifact just built by your own project.

How do include JUnit test cases as a part of Maven build?

I have existing JUnit4 test cases which I run from Eclipse and as a part of Maven. Now I am looking to perform stress tests by leveraging them. I noticed Maven is not packaging them as a part of the build. How do I go about it?
This will attach the tests (and their sources) in a separate jar:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-source-plugin</artifactId>
<executions>
<execution>
<id>attach-sources</id>
<goals>
<goal>jar</goal>
</goals>
</execution>
<execution>
<id>attach-test-sources</id>
<goals>
<goal>test-jar</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<executions>
<execution>
<id>test-jar</id>
<goals>
<goal>test-jar</goal>
</goals>
</execution>
</executions>
</plugin>
Afterwards you can use them as a dependency by using the type test-jar.
