Maven Bundle Plugin Provides a maven plugin that supports creating an OSGi bundle from the contents of the compilation classpath along with its resources and dependencies. Plus a zillion other features.
What is the Maven BND plugin?
This Maven plugin is based on the BND tool from Peter Kriens. The way BND works is by treating your project as a big collection of classes (e.g., project code, dependencies, and the class path). The way you create a bundle with BND is to tell it the content of the bundle's JAR file as a subset of the available classes.
Which Maven plugin is used for project reports?
Project Reports Maven Bundle Plugin This Maven plugin is based on the BNDtool from Peter Kriens. The way BND works is by treating your project as a big collection of classes (e.g., project code, dependencies, and the class path).
How do I configure the Maven bundle plugin to work with Eclipse?
It is possible to configure the Maven Bundle Plugin to put the bundle manifest where Eclipse/PDE expects it, and use the Maven Dependency Plugin to arrange for any embedded dependencies to appear in a local directory that matches the Bundle-ClassPath entries. Here is an example POM that does this:
What is the assembly plugin for Maven?
The Assembly Plugin for Maven enables developers to combine project output into a single distributable archive that also contains dependencies, modules, site documentation, and other files. Your project can easily build distribution "assemblies" using one of the prefabricated assembly descriptors.
What is bundle maven?

What are the different types of plugins in Maven?
Maven has two types of plugins:Build – executed during the build process. Examples include Clean, Install, and Surefire plugins. These should be configured in the build section of the POM.Reporting – executed during site generation to produce various project reports. Examples include Javadoc and Checkstyle plugins.
What is the difference between plugins and dependencies in Maven?
A plugin is an extension to Maven, something used to produce your artifact (maven-jar-plugin for an example, is used to, you guess it, make a jar out of your compiled classes and resources). A dependency is a library that is needed by the application you are building, at compile and/or test and/or runtime time.
What are Maven build plugins?
What is a Plugin? "Maven" is really just a core framework for a collection of Maven Plugins. In other words, plugins are where much of the real action is performed, plugins are used to: create jar files, create war files, compile code, unit test code, create project documentation, and on and on.
What is POM XML?
A Project Object Model or POM is the fundamental unit of work in Maven. It is an XML file that contains information about the project and configuration details used by Maven to build the project. It contains default values for most projects.
What is Maven resources plugin?
The Resources Plugin handles the copying of project resources to the output directory. There are two different kinds of resources: main resources and test resources.
What does OSGi stand for?
Open Service Gateway InitiativeThe OSGi (Open Service Gateway Initiative) specification is a Java framework for developing and deploying modular software programs and libraries.
Is OSGi a Microservice?
OSGI is an application architecture, while microservices is a distributed systems concept. In my experience, microservices offer a number of benefits: Individual microservices are easy to deploy, test, and maintain. Microservices are language agnostic.
What is OSGi framework Java?
OSGi defines a dynamic module system for Java™. The OSGi service platform has a layered architecture, and is designed to run on various standard Java profiles. OSGi Applications deployed to WebSphere® Application Server run on an Enterprise Java profile that is provided as part of the server runtime environment.
Which Maven plugin Jenkins install?
The Maven Plugin is a plugin that provides the capabilities to configure, build, and run Maven-based projects in Jenkins. This is a must pre-requisite for the integration of Maven with Jenkins.
Which Maven plugin do we use when we create a Maven project?
The Maven Clean plugin (maven-clean-plugin) is responsible for removing the target directory of a Maven project. When you run "mvn clean", Maven executes the "clean" goal as defined in the Clean plug-in, and the target directory is removed.
What does surefire plugin do in Apache Maven?
The Surefire Plugin is used during the test phase of the build lifecycle to execute the unit tests of an application. It generates reports in two different file formats: Plain text files (*. txt)
What is Maven failsafe plugin used for?
The Failsafe Plugin is used during the integration-test and verify phases of the build lifecycle to execute the integration tests of an application. The Failsafe Plugin will not fail the build during the integration-test phase, thus enabling the post-integration-test phase to execute.
How to get around Maven bundle?
The easiest way to get around this Maven 'feature' is to unpack the contents of the bundle to the output directory after the packaging step, so the additional classes will be found where Maven expects them. Thankfully there is now an easy option to do this in the bundle-plugin:
What is BND in Maven?
The BND library underlying the plugin defines instructions to direct its behavior. For this Maven plugin, these instructions are issued in the plugin configuration section of the POM file, as was illustrated above . BND recognizes three types of instructions:
How to find remote OBR in Maven?
The remote OBR is found by querying the <distributionManagement> section of the project, unless -DaltDeploymentRepository is set. See http://maven.apache.org/plugins/maven-deploy-plugin/deploy-mojo.html for more details about these particular settings.
What is BND plugin?
The way you create a bundle with BND is to tell it the content of the bundle’s JAR file as a subset of the available classes. This plugin wraps BND to make it work specifically with the Maven 2 project structure and to provide it with reasonable default behavior for Maven 2 projects.
When to use BND?
Bnd will use it when calculating the bundle contents, and will also copy across all manifest attributes starting with a capital letter. As shown in the above example, you could use this to include a non-OSGi manifest which you then customize with extra OSGi attributes.
Can you create bundles in Maven?
Once in a while you may create a bundle which contains additional classes to the ones compiled from src/main/java, for example when you embed the classes from another jar. This can sometimes cause unforeseen problems in Maven, as it will use the output directory ( target/classes) rather than the final bundle, when compiling against projects in the same reactor (ie. the same build).
Can you export packages from an embedded dependency?
If you embed a dependency with <Embed-Dependency>, and your <Export-Package> or <Private-Package> instructions match packages inside the embedded jar, you will see some duplication inside the bundle. This is because the <Export-Package> and <Private-Package> instructions will result in classes being inlined in the bundle, even though they also exist inside the embedded jar. If you want to export packages from an embedded dependency without such duplication then you can either inline the dependency, or use a new BND instruction called <_exportcontents>.
What is assembly plugin?
The Assembly Plugin for Maven enables developers to combine project output into a single distributable archive that also contains dependencies, modules, site documentation, and other files.
What is the main goal of the assembly plugin?
The main goal in the assembly plugin is the single goal. It is used to create all assemblies.
What is the build tool in Maven?
The build tool is the first subset in the Maven where the artifacts are deployed in the server and enable the automation and the integration of the build tools. Next is the task of managing the resources, plugins, and the dependencies in a project which is done by the Dependency Management. The scope of dependency should be known beforehand to avoid any conflict in the use of the dependency for a particular instance. The Project Management is the third subset of the Apache Maven consisting of the pom.xml file. Proper documentation of the code and information about various aspects like missing tasks, versions, etc. could be maintained in this phase. The consistency is maintained across different projects in Maven as every project maintains a standardized directory.
Where are Apache Maven plugins maintained?
The Apache Maven plugins are up to date and are maintained in the org/apache/maven/plugins/ subfolder. The organization of the package follows a standard directory structure resembling the naming convention of the Java package.
What is pom.xml in Maven?
In Apace Maven, the pom.xml file is the most important file where the required dependencies for a project such as Hibernate need to be mentioned. Next is the ArtifactId or the GroupId which ensures each project in the Maven is unique. The package used for the project is described by the combination of ArtifactId with the GroupId.
How does Maven maintain projects?
As seen earlier, Maven provides a standardized way to maintain each project by proving all the necessary JAR files, and dependencies in its repository and separates one project from another via a unique id.
What is Maven repository?
