    copied!<p>Is there any way to generate the JPA 2.0 metamodel via maven without having a persistence.xml file. I'm using eclipselink.</p> <p>In my Java EE-projects I'm doing something like the following wich works fine because in that case I have a persistence.xml.</p> <pre><code>&lt;plugin&gt; &lt;groupId&gt;org.bsc.maven&lt;/groupId&gt; &lt;artifactId&gt;maven-processor-plugin&lt;/artifactId&gt; &lt;version&gt;2.0.5&lt;/version&gt; &lt;executions&gt; &lt;execution&gt; &lt;id&gt;process&lt;/id&gt; &lt;goals&gt; &lt;goal&gt;process&lt;/goal&gt; &lt;/goals&gt; &lt;phase&gt;generate-sources&lt;/phase&gt; &lt;configuration&gt; &lt;!-- there must no line break between the two compiler arguments! --&gt; &lt;compilerArguments&gt;-Aeclipselink.persistencexml=${basedir}/src/main/resources/META-INF/persistence.xml&lt;/compilerArguments&gt; &lt;processors&gt; &lt;processor&gt;org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor&lt;/processor&gt; &lt;/processors&gt; &lt;/configuration&gt; &lt;/execution&gt; &lt;/executions&gt; &lt;dependencies&gt; &lt;dependency&gt; &lt;groupId&gt;org.eclipse.persistence&lt;/groupId&gt; &lt;artifactId&gt;javax.persistence&lt;/artifactId&gt; &lt;version&gt;2.0.3&lt;/version&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;org.eclipse.persistence&lt;/groupId&gt; &lt;artifactId&gt;org.eclipse.persistence.jpa.modelgen&lt;/artifactId&gt; &lt;version&gt;2.3.2&lt;/version&gt; &lt;/dependency&gt; &lt;/dependencies&gt; &lt;/plugin&gt; </code></pre> <p>Now I have a spring project which configures the jpa via spring context. Is the only way to create the metamodel to create a persistence.xml or can I somehow stay with the configuration in the spring context?</p>
