<blockquote> 2) the eclipse not take me M2_REPO variable (in another workspace it works) I have added the variable and the jar. </blockquote> For every workspace, you need to call <a href="http://maven.apache.org/plugins/maven-eclipse-plugin/configure-workspace-mojo.html" rel="nofollow"><code>mvn eclipse:configure-workspace</code></a> once. This initializes the <code>M2_REPO</code> variable. <blockquote> 3) Description Resource Path Location Type Java compiler level does not match the version of the installed Java project facet. PropiedadesArg Unknown Faceted Project Problem (Java Version Mismatch) </blockquote> The compiler level is taken from the pom configuration of the maven compiler plugin. Example (for 1.6 compliance): <pre><code><plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>2.3.2</version> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> </code></pre> <hr> But apart from that: <code>mvn eclipse:eclipse</code> shouldn't be used any more, <a href="http://m2eclipse.sonatype.org/" rel="nofollow">m2eclipse</a> is the way to go for Eclipse + Maven. It uses an embedded Maven installation to actually run the maven build (or parts of it) in Eclipse, whereas the Maven Eclipse Plugin just configures Eclipse from the outside. Here's a <a href="http://maven.40175.n5.nabble.com/Preparing-for-M2Eclipse-1-0-amp-no-support-for-the-maven-eclipse-plugin-td139921.html" rel="nofollow">thread were the Maven founders discuss this topic</a>. <hr> Also: <pre><code>mvn archetype:create -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-webapp -DarchetypeVersion=1.0 -DgroupOd=ar.com -DartifactId=RETOP ^^^^^^^ </code></pre> here's a typo, it's <code>groupId</code>, not <code>groupOd</code> <hr> Oh, now I get it. <code>eclipse:eclipse</code> uses the variable <code>MAVEN_REPO</code>, not <code>M2_REPO</code> (<code>M2_REPO</code> is created and maintained by m2eclipse). Anyway, in Eclipse, select <code>Window > Preferences > Java > Build Path > Classpath Variables</code>, add or edit the <code>M2_REPO</code> variable and set it to <code><path to your home directory>/.m2/repository</code>, e.g. <code>C://users/yournamehere/.m2/repository</code>

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.
