=== Using the karaf-maven-plugin

The Karaf Maven plugin allows you:

* to work with Karaf features: verify and validate a features descriptor, add features bundle into a repository, create a KAR archive from a features descriptor, etc.
* to create Karaf commands help: it generates help from Karaf commands
* to modify Karaf instances and create distributions

See https://github.com/apache/karaf/blob/master/examples/karaf-maven-example/README.md for details.

==== Packaging

The most generally useful features of the karaf-maven-plugin are exposed as packagings.  To use the packagings the pom or an ancestor must configure the karaf-maven-plugin with extensions:

----
    <build>
        <pluginManagement>
            <plugins>
                <plugin>
                    <groupId>org.apache.karaf.tooling</groupId>
                    <artifactId>karaf-maven-plugin</artifactId>
                    <version>${project.version}</version>
                    <extensions>true</extensions>
                </plugin>
            </plugins>
        </pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.apache.karaf.tooling</groupId>
                <artifactId>karaf-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
----

Then specify the packaging in your project as usual, e.g.

----
    <packaging>kar</packaging>
----

|===
|Packaging |Description

|feature
|The feature packaging verifies a features.xml descriptor using the `karaf:verify` goal.

|kar
|The kar packaging generates a features.xml descriptor using the `karaf:features-generate-descriptor` and then packages a kar using the `karaf:features-create-kar` goal.

|karaf-assembly
|Assembles a Karaf server based on the features descriptors and kar files listed as Maven dependencies.
|===

==== Commands goals

The `karaf-maven-plugin` is able to generate documentation for Karaf commands

===== `karaf:commands-generate-help`

The `karaf:commands-generate-help` goal generates documentation containing Karaf commands help.

It looks for Karaf commands in the current project class loader and generates the help as displayed with the `--help`
option in the Karaf shell console.

====== Example

The example below generates help for the commands in the current project:

----
<project>
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.karaf.tooling</groupId>
        <artifactId>karaf-maven-plugin</artifactId>
        <version>${project.version}</version>

        <executions>
          <execution>
            <id>document-commands</id>
            <phase>generate-resources</phase>
            <goals>
              <goal>commands-generate-help</goal>
            </goals>
            <configuration>
              <targetFolder>${project.build.directory}/docbook/sources</targetFolder>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</project>
----

====== Parameters

|===
|Name |Type |Description

|`targetFolder`
|`File`
|The directory where the documentation output files are to be generated. Default value: ${project.build.directory}/docbkx/sources

|`format`
|`String`
|The output format (docbx, asciidoc, or conf) of the commands documentation. Default value: docbx

|`classLoader`
|`String`
|The class loader to use in loading the commands. Default value: ${project}
|===

==== Features and kar goals

[NOTE]
====
You should use the features or kar packaging instead of these individual goals.
====

The `karaf-maven-plugin` provides several goals to help you create and verify features XML descriptors as well as leverage your features to create a custom Karaf distribution.

===== `karaf:features-generate-descriptor`

The `karaf:features-generate-descriptor` goal generates a features XML file based on the Maven dependencies.
By default, it will follow Maven transitive dependencies, stopping when it encounters bundles already present in features that are Maven dependencies.

A record of the dependency tree search can be found in target/history/treeListing.txt.

You can track dependency changes and warn or fail on change.

====== Configuration

Specify the packaging as a top level element

----
<packaging>feature</packaging>
----

You can supply a feature descriptor to extend in `src/main/feature/feature.xml`.

|===
|Parameter Name |Type |Description

|aggregateFeatures
|boolean (false)
|Specifies processing of feature repositories that are (transitive) Maven dependencies.
If false, all features in these repositories become dependencies of the generated feature.
If true, all features in these repositories are copied into the generated feature repository.

|startLevel
|int
|The start level for the bundles determined from Maven dependencies.
This can be overridden by specifying the bundle in the source feature.xml with the desired startlevel.

|includeTransitiveDependency
|boolean (true)
|Whether to follow Maven transitive dependencies.

|checkDependencyChange
|boolean (false)
|Whether to record dependencies in `src/main/history/dependencies.xml` for change tracking.

|warnOnDependencyChange
|boolean (false)
|whether to fail on changed dependencies (false, default) or warn in the build output (true).

|logDependencyChanges
|boolean (false)
|If true, added and removed dependencies are shown in `target/history`.

|overwriteChangedDependencies
|boolean (false)
|If true, the `src/main/history/dependencies.xml` file will be overwritten if it has changed.

|markRuntimeScopeAsDependency
|boolean (true)
|Whether to mark dependencies' in the `runtime` scope with `dependency="true"`.

|markTransitiveAsDependency
|boolean (false)
|Whether to mark transitive dependencies' with `dependency="true"`.
|If true, the `src/main/history/dependencies.xml` file will be overwritten if it has changed.
|===

        </executions>
      </plugin>
    </plugins>
  </build>
</project>
----

===== `karaf:verify`

Except in unusual circumstances, use the `<packaging>feature</packaging>` to run this goal.

The `karaf:verify` goal verifies and validates a features XML descriptor by checking if all the required imports
for the bundles defined in the features can be matched to a provided export.

By default, the plugin tries to add the Karaf core features (standard and enterprise) in the repositories set.
It means that it's not required to explicitly define the Karaf features descriptor in the repository section of
your features descriptor.

====== Example

The example below validates the features defined in the `target/features.xml` by checking all the imports and exports.
It reads the definition for the packages that are exported by the system bundle from the `src/main/resources/config.properties` file.

====== Parameters

|===
|Name |Type |Description

|`descriptors`
|`String[]`
|The list of features XML repositories to use for the verify

|`features`
|`String[]`
|The list of features to verify. If not specified, all features in the descriptors will be verified.

|`framework`
|`String[]`
|The features providing the Karaf framework (optional)

|`javase`
|`String`
|The Java version to use for the verify

|===

===== `karaf:features-add-to-repository`

Consider using the karaf-assembly packaging which makes it easy to assemble a custom distribution in one step instead
of this individual goal.

The `karaf:features-add-to-repository` goal adds all the required bundles for a given set of features into directory.
You can use this goal to create a `/system` directory for building your own Karaf-based distribution.

By default, the Karaf core features descriptors (standard and enterprise) are automatically included in the descriptors set.

====== Example

The example below copies the bundles for the `spring` and `war` features defined in the Karaf features XML descriptor
into the `target/features-repo` directory.

====== Parameters

|===
|Name |Type |Description

|`descriptors`
|`String[]`
|List of features XML descriptors where the features are defined

|`features`
|`String[]`
|List of features that bundles should be copied to the repository directory

|`repository`
|`File`
|The directory where the bundles will be copied by the plugin goal

|`timestampedSnapshot`
|`boolean`
|For SNAPSHOT artifacts, if false we use the base version (foo-1.0-SNAPSHOT), else we use the timestamped version (foo-1.0-2019xxxx). Default value: false
|===

===== `karaf:create-kar`

[NOTE]
====
Except in unusual circumstances, use the `<packaging>kar</packaging>` to run this goal.
====

The `karaf:kar` goal assembles a KAR archive from a features XML descriptor file, normally generated in the same project
with the `karaf:features-generate-descriptor` goal.

There are two important directories in a kar:

* `repository/`  contains a Maven structured repository of artifacts to be copied into the Karaf repository.
The features descriptor and all the bundles mentioned in it are installed in this directory.
* `resources/` contains other resources to be copied over the Karaf installation.

Everything in `target/classes` is copied into the kar.
Therefore resources you want installed into Karaf need to be in e.g. `src/main/resources/resources`.
This choice is so other resources such as legal files from the maven-remote-resources-plugin can be included under
META-INF in the kar, without getting installed into Karaf.

====== Example

----
<project>
...
  <packaging>kar</packaging>
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.karaf.tooling</groupId>
        <artifactId>karaf-maven-plugin</artifactId>
        <version>${project.version}</version>
        <extensions>true</extensions>
        <!-- There is no useful configuration for the kar mojo. The features-generate-descriptor mojo configuration may be useful -->
      </plugin>
    </plugins>
  </build>
</project>
----

===== `karaf:install-kar`

==== Instances and distributions goals

The `karaf-maven-plugin` helps you to build custom Karaf distributions or archives existing Karaf instances:

===== `karaf:assembly`

[NOTE]
====
This goal is run as part of the karaf-assembly packaging.
====

The `karaf:assembly` goal creates a Karaf instance (assembly) filesystem using the Maven dependencies and a provided configuration.

By default, the generated Karaf instance is a dynamic distribution (it's started with default set of resources and then you can deploy new applications in this instance).

It's also possible to generate a Karaf instance as a static distribution (kind of immutable):
