    copied!<p>can any one tell me how to force maven to precede mapping .hbm.xml files in the automatically generated hibernate.cfg.xml file with package path?</p> <p>My general idea is, I'd like to use hibernate-tools via maven to generate the persistence layer for my application. So, I need the hibernate.cfg.xml, then all my_table_names.hbm.xml and at the end the POJO's generated. Yet, the <code>hbm2java</code> goal won't work as I put *.hbm.xml files into the <code>src/main/resources/package/path/</code> folder but <code>hbm2cfgxml</code> specifies the mapping files only by table name, i.e.:</p> <pre><code>&lt;mapping resource="MyTableName.hbm.xml" /&gt; </code></pre> <p>So the big question is: how can I configure <code>hbm2cfgxml</code> so that hibernate.cfg.xml looks like below:</p> <pre><code>&lt;mapping resource="package/path/MyTableName.hbm.xml" /&gt; </code></pre> <p>My pom.xml looks like this at the moment:</p> <pre><code>&lt;plugin&gt; &lt;groupId&gt;org.codehaus.mojo&lt;/groupId&gt; &lt;artifactId&gt;hibernate3-maven-plugin&lt;/artifactId&gt; &lt;version&gt;2.2&lt;/version&gt; &lt;executions&gt; &lt;execution&gt; &lt;id&gt;hbm2cfgxml&lt;/id&gt; &lt;phase&gt;generate-sources&lt;/phase&gt; &lt;goals&gt; &lt;goal&gt;hbm2cfgxml&lt;/goal&gt; &lt;/goals&gt; &lt;inherited&gt;false&lt;/inherited&gt; &lt;configuration&gt; &lt;components&gt; &lt;component&gt; &lt;name&gt;hbm2cfgxml&lt;/name&gt; &lt;implemetation&gt;jdbcconfiguration&lt;/implementation&gt; &lt;outputDirectory&gt;src/main/resources/&lt;/outputDirectory&gt; &lt;/component&gt; &lt;/components&gt; &lt;componentProperties&gt; &lt;packagename&gt;package.path&lt;/packageName&gt; &lt;configurationFile&gt;src/main/resources/hibernate.cfg.xml&lt;/configurationFile&gt; &lt;/componentProperties&gt; &lt;/configuration&gt; &lt;/execution&gt; &lt;/executions&gt; &lt;/plugin&gt; </code></pre> <p>And then the second question: is there a way to tell maven to copy resources to the target folder before executing <code>hbm2java</code>? At the moment I'm using</p> <pre><code>mvn clean resources:resources generate-sources </code></pre> <p>for that, but there must be a better way.</p> <p>Thanks for any help.</p> <p><strong>Update:</strong></p> <p><strong>@Pascal:</strong> Thank you for your help. The path to mappings works fine now, I don't know what was wrong before, though. Maybe there is some issue with writing to hibernate.cfg.xml while reading database config from it (though the file gets updated).</p> <p>I've deleted the file hibernate.cfg.xml, replaced it with database.properties and run the goals <code>hbm2cfgxml</code> and <code>hbm2hbmxml</code>. I also don't use the <code>outputDirectory</code> nor <code>configurationfile</code> in those goals anymore.</p> <p>As a result the files <code>hibernate.cfg.xml</code> and all <code>*.hbm.xml</code> are being generated into my target/hibernate3/generated-mappings/ folder, which is the default value. Then I updated the <code>hbm2java</code> goal with the following:</p> <pre><code>&lt;componentProperties&gt; &lt;packagename&gt;package.name&lt;/packagename&gt; &lt;configurationfile&gt;target/hibernate3/generated-mappings/hibernate.cfg.xml&lt;/configurationfile&gt; &lt;/componentProperties&gt; </code></pre> <p>But then I get the following:</p> <pre><code>[INFO] --- hibernate3-maven-plugin:2.2:hbm2java (hbm2java) @ project.persistence --- [INFO] using configuration task. [INFO] Configuration XML file loaded: file:/C:/Documents%20and%20Settings/mmm/workspace/project.persistence/target/hibernate3/generated-mappings/hibernate.cfg.xml 12:15:17,484 INFO org.hibernate.cfg.Configuration - configuring from url: file:/C:/Documents%20and%20Settings/mmm/workspace/project.persistence/target/hibernate3/generated-mappings/hibernate.cfg.xml 12:15:19,046 INFO org.hibernate.cfg.Configuration - Reading mappings from resource : package.name/Messages.hbm.xml [INFO] ------------------------------------------------------------------------ [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [ERROR] Failed to execute goal org.codehaus.mojo:hibernate3-maven-plugin:2.2:hbm2java (hbm2java) on project project.persistence: Execution hbm2java of goal org.codehaus.mojo:hibernate3-maven-plugin:2.2:hbm2java failed: resource: package/name/Messages.hbm.xml not found </code></pre> <p>How do I deal with that? Of course I could add:</p> <pre><code>&lt;outputDirectory&gt;src/main/resources/package/name&lt;/outputDirectory&gt; </code></pre> <p>to the <code>hbm2hbmxml</code> goal, but I think this is not the best approach, or is it? Is there a way to keep <strong>all</strong> the generated code and resources away from the <code>src/</code> folder?</p> <p>I assume, the goal of this approach is not to generate any sources into my src/main/java or /resources folder, but to keep the generated code in the target folder. As I generally agree with this point of view, I'd like to continue with that eventually executing <code>hbm2dao</code> and packaging the project to be used as a generated persistence layer component from the business layer. Is this also what you meant?</p>
