  1. POProblems with maven built OSGi including dependencies
    text
    copied!<p>I'm currently starting with OSGi, iPOJO and iPOJO Annotations and trying to build a simple component to be deployed in Felix. Unfortunately, I'm stumbling over various problems which take me hours to solve or which I cannot even solve after wasting hours, like the following:</p> <p>I want to use an existing library in my OSGi bundle which we build using Maven. The library is currently not "OSGI-ified" and we are not planning to do so in the medium term. Because of that, I want to include this library and all of its dependencies in the bundle, using …:</p> <pre><code>&lt;Embed-Dependency&gt;*&lt;/Embed-Dependency&gt; &lt;Embed-Transitive&gt;true&lt;/Embed-Transitive&gt; </code></pre> <p>What I have now, is the following pom.xml file for the OSGi component:</p> <pre><code>&lt;project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"&gt; &lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt; &lt;groupId&gt;foo&lt;/groupId&gt; &lt;artifactId&gt;samplecomponent&lt;/artifactId&gt; &lt;packaging&gt;bundle&lt;/packaging&gt; &lt;version&gt;0.0.1-SNAPSHOT&lt;/version&gt; &lt;build&gt; &lt;plugins&gt; &lt;plugin&gt; &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt; &lt;artifactId&gt;maven-compiler-plugin&lt;/artifactId&gt; &lt;version&gt;2.3.2&lt;/version&gt; &lt;configuration&gt; &lt;compilerArgument&gt;-Xlint:all&lt;/compilerArgument&gt; &lt;showWarnings&gt;true&lt;/showWarnings&gt; &lt;source&gt;1.6&lt;/source&gt; &lt;target&gt;1.6&lt;/target&gt; &lt;compilerArguments&gt; &lt;encoding&gt;UTF-8&lt;/encoding&gt; &lt;/compilerArguments&gt; &lt;showDeprecation&gt;true&lt;/showDeprecation&gt; &lt;verbose&gt;true&lt;/verbose&gt; &lt;encoding&gt;UTF-8&lt;/encoding&gt; &lt;/configuration&gt; &lt;/plugin&gt; &lt;plugin&gt; &lt;groupId&gt;org.apache.felix&lt;/groupId&gt; &lt;artifactId&gt;maven-bundle-plugin&lt;/artifactId&gt; &lt;extensions&gt;true&lt;/extensions&gt; &lt;version&gt;2.3.6&lt;/version&gt; &lt;configuration&gt; &lt;instructions&gt; &lt;Bundle-SymbolicName&gt;${project.artifactId}&lt;/Bundle-SymbolicName&gt; &lt;Embed-Dependency&gt;*&lt;/Embed-Dependency&gt; &lt;Embed-Transitive&gt;true&lt;/Embed-Transitive&gt; &lt;Embed-Directory&gt;lib&lt;/Embed-Directory&gt; &lt;Export-Package&gt;*&lt;/Export-Package&gt; &lt;_exportcontents&gt;*&lt;/_exportcontents&gt; &lt;/instructions&gt; &lt;/configuration&gt; &lt;/plugin&gt; &lt;plugin&gt; &lt;groupId&gt;org.apache.felix&lt;/groupId&gt; &lt;artifactId&gt;maven-ipojo-plugin&lt;/artifactId&gt; &lt;version&gt;1.6.0&lt;/version&gt; &lt;executions&gt; &lt;execution&gt; &lt;goals&gt; &lt;goal&gt;ipojo-bundle&lt;/goal&gt; &lt;/goals&gt; &lt;/execution&gt; &lt;/executions&gt; &lt;/plugin&gt; &lt;/plugins&gt; &lt;/build&gt; &lt;dependencies&gt; &lt;dependency&gt; &lt;groupId&gt;org.apache.felix&lt;/groupId&gt; &lt;artifactId&gt;org.apache.felix.ipojo.annotations&lt;/artifactId&gt; &lt;version&gt;1.8.0&lt;/version&gt; &lt;scope&gt;provided&lt;/scope&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;foo&lt;/groupId&gt; &lt;artifactId&gt;mylibrary&lt;/artifactId&gt; &lt;version&gt;1.2.3&lt;/version&gt; &lt;scope&gt;compile&lt;/scope&gt; &lt;/dependency&gt; &lt;/dependencies&gt; &lt;/project&gt; </code></pre> <p>The bundle jar file is built without any problems, but when deploying and starting the bundle on Apache Felix, I get the following error:</p> <pre><code>g! install file:/…/samplecomponent-0.0.1-SNAPSHOT.jar Bundle ID: 8 g! start 8 org.osgi.framework.BundleException: Unresolved constraint in bundle samplecomponent [8]: Unable to resolve 8.0: missing requirement [8.0] osgi.wiring.package; (osgi.wiring.package=com.sun.jdmk.comm) </code></pre> <p>I have set the log level to the highest verbosity, no more information unfortunately. When I remove mylibrary, the bundle is started without problems.</p> <p>Any suggestions appreciated!</p>
