[confluence]

Page Edited : FELIX : Apache Felix Maven OBR Plugin Apache Felix Maven OBR Plugin has been edited by Richard S. Hall (Mar 09, 2008). (View changes) Content: The maven-obr-plugin is deprecated and its features have been merged into the 1.4.0 release of the maven-bundle-plugin This Maven plug-in aims to automate OBR (OSGi Bundle Repository) management. It helps manage a local OBR for your local Maven repository, and also supports remote OBRs for bundle distribution. The plug-in automatically computes bundle capabilities and requirements, using a combination of Bindex and Maven metadata. Features The maven-obr-plugin supports: Management of both local and remote OBRs Registering Maven and non-Maven artifacts with OBRs Automatically discovering bundle capabilities and requirements Customizing bundle descriptions How to use the maven-obr-plugin? The plug-in offers five Maven goals: install adds the current bundle project to the local OBR install-file adds a local bundle file to the local OBR deploy adds the current bundle project to a remote OBR deploy-file adds a local bundle file to a remote OBR clean cleans the local OBR, removing missing bundles Any of these goals can be disabled by setting -DobrRepository=NONE obr:install The install goal updates the local OBR with the details of the installed bundle from the local Maven repository. (If the project has an obr.xml file somewhere in its resources, then it will be automatically detected and applied.) configuration: obrRepository path to local OBR, defaults to <local-maven-repository>/repository.xml To attach this goal to your project's lifecycle, use: <plugin> <groupId>org.apache.felix</groupId> <artifactId>maven-obr-plugin</artifactId> <version>1.2.0</version> <executions> <execution> <goals> <goal>install</goal> </goals> </execution> </executions> </plugin> obr:install-file The install-file goal updates the local OBR with the details of a bundle from the local filesystem. configuration: obrRepository path to local OBR, defaults to <local-maven-repository>/repository.xml groupId Maven groupId for the bundle, taken from pomFile if given artifactId Maven artifactId for the bundle, taken from pomFile if given version Maven version for the bundle, taken from pomFile if given packaging Maven packaging type for the bundle, taken from pomFile if given classifier Maven classifier type, defaults to none pomFile optional Pom file describing the bundle file bundle file, defaults to the bundle from the local Maven repository obrXml optional additional properties for the bundle Example: mvn org.apache.felix:maven-obr-plugin:1.2.0:install-file \ -DpomFile=myPom.xml -Dfile=foo-1.0.jar obr:deploy The deploy goal updates the remote OBR with the details of the deployed bundle from the local Maven repository. 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. (If the project has an obr.xml file somewhere in its resources, then it will be automatically detected and applied.) configuration: obrRepository name of remote OBR, defaults to repository.xml altDeploymentRepository alternative remote repository, id::layout::url ignoreLock ignore remote locking when updating the OBR To attach this goal to your project's lifecycle, use: <plugin> <groupId>org.apache.felix</groupId> <artifactId>maven-obr-plugin</artifactId> <version>1.2.0</version> <executions> <execution> <goals> <goal>deploy</goal> </goals> </execution> </executions> </plugin> obr:deploy-file The deploy-file goal updates the remote OBR with the details of a deployed bundle from the local filesystem. The remote OBR is found using the -DrepositoryId and -Durl parameters. See http://maven.apache.org/plugins/maven-deploy-plugin/deploy-file-mojo.html for more details about these particular settings. You can use the -DbundleUrl parameter to give the public location of the deployed bundle, which may differ from the remote OBR location. configuration: obrRepository name of remote OBR, defaults to repository.xml repositoryId optional repository id, used to lookup authentication settings url remote repository transport URL, like scpexe://host/path/to/obr bundleUrl public URL of deployed bundle, like http://www.foo.org/bundles/foo.jar groupId Maven groupId for the bundle, taken from pomFile if given artifactId Maven artifactId for the bundle, taken from pomFile if given version Maven version for the bundle, taken from pomFile if given packaging Maven packaging type for the bundle, taken from pomFile if given classifier Maven classifier type, defaults to none pomFile optional Pom file describing the bundle file bundle file, defaults to the bundle from the local Maven repository obrXml optional additional properties for the bundle ignoreLock ignore remote locking when updating the OBR Example: mvn org.apache.felix:maven-obr-plugin:1.2.0:deploy-file \ -DpomFile=myPom.xml -Dfile=foo-1.0.jar -Durl=file:/tmp/example/OBR \ -DbundleUrl=http://www.foo.org/bundles/foo.jar obr:clean Sometimes you would like to clean your local OBR because it contains bundles that are no longer in your local Maven repository. This case often occurs when artifacts were deleted manually. The maven-obr-plugin provides a simple goal to check for missing bundles, and remove them from the local OBR. configuration: obrRepository path to local OBR, defaults to <local-maven-repository>{}/repository.xml To attach this goal to your project's lifecycle, use: <plugin> <groupId>org.apache.felix</groupId> <artifactId>maven-obr-plugin</artifactId> <version>1.2.0</version> <executions> <execution> <goals> <goal>clean</goal> </goals> </execution> </executions> </plugin> Concurrent updates With a remote OBR, several uploads may occur at the same time. However, the remote OBR is centralized in one file, so concurrent modification must be avoided. To achieve this, the plug-in implements a locking system. Each time the plug-in tries to modify the file it sets a file based lock. If it can't take the lock, it will wait and retry. After 3 attempts the upload process fails. To bypass this lock add -DignoreLock to the command-line (or add <ignoreLock>true<ignoreLock> to the configuration section of your Pom). FTP protocol Not all protocols are supported by Maven out of the box. For example the ftp protocol requires the wagon-ftp component. To enable the ftp protocol add this to your Pom: <build> <extensions> <extension> <groupId>org.apache.maven.wagon</groupId> <artifactId>wagon-ftp</artifactId> <version>1.0-alpha-6</version> </extension> </extensions> </build> How the plug-in computes the description of the bundle The description of the bundle comes from three different sources: Bindex : Bindex is a tool that analyzes a bundle manifest to generate OBR description pom.xml : by analyzing the pom file, various information is collected (symbolic name ...) obr.xml : this file contains customized description and capabilities for the bundle These sources are merged together using the following precedence: Bindex | (overrides) pom.xml | (overrides) obr.xml A warning message is displayed when existing information is overridden. Known issues & limitations obr.xml (file given by the user to add properties not found by Bindex) must be correct, because the plug-in does not check its syntax.
