    <p>I get the following error running the maven build for Apache Sling, even with the recommended heap size:</p> <pre><code>main: [echo] **************** WARNING (SLING-443/SLING-1782) ****************************** [echo] On most platforms, you'll get OutOfMemoryErrors when building unless you set [echo] on 32bit platforms: MAVEN_OPTS="-Xmx256M -XX:MaxPermSize=256M", see SLING-443 [echo] on 64bit platforms: MAVEN_OPTS="-Xmx512M -XX:MaxPermSize=512M", see SLING-1782 [echo] ****************************************************************************** [INFO] Executed tasks [INFO] [INFO] --- maven-resources-plugin:2.4.3:testResources (default-testResources) @ sling-launchpad-webapp-archetype --- [INFO] Using 'UTF-8' encoding to copy filtered resources.

[ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles: [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/OutOfMemoryError </code></pre> <p>Sure enough my heap size is the same that they recommend on the project homepage:</p> <pre><code>echo $MAVEN_OPTS -Xmx512M -XX:MaxPermSize=512m </code></pre> <p>I suspect that the cause is that maven is forking and the jvm in the child process does not have the same heap size - however I cannot identify which plugin is forking from the console output.</p> <p>Any ideas appreciated !!! Thanks </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
