    <p>I have a multi module web application.</p> <p>The structure is:</p> <pre><code>Parent | | - - Child 1 | - - Child 2 | - - Web </code></pre> <p>And the web project depends on the two child modules</p> <p>When using my IDE to build my project I was used to the IDE building the classes in the WEB-INF/classes folder. This was nice as the web server noticed the new classes and either restarted or hot deployed these files. With maven it seems that I have to package the whole thing from scratch every time. </p> <p>I would like to find a way in maven such that i can avoid running mvn:clean mvn:install mvn:war:inplace. Instead I would like a mvn:comile, and then the stuff just there. </p> <p>I hope you understand what I mean. Testing the web app is extremely slow when you always have to build all the project jars and run som war command before things are updated. </p> <p>The web apps pom:</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/maven-v4_0_0.xsd"&gt; &lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt; &lt;parent&gt; ... &lt;/parent&gt; &lt;artifactId&gt;web&lt;/artifactId&gt; &lt;packaging&gt;war&lt;/packaging&gt; &lt;dependencies&gt; &lt;dependency&gt; &lt;groupId&gt;bla.bla.bla&lt;/groupId&gt; &lt;artifactId&gt;bla_child1&lt;/artifactId&gt; &lt;version&gt;1.0-SNAPSHOT&lt;/version&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;bla.bla.bla&lt;/groupId&gt; &lt;artifactId&gt;bla_child2&lt;/artifactId&gt; &lt;version&gt;1.0-SNAPSHOT&lt;/version&gt; &lt;/dependency&gt; &lt;/dependencies&gt; &lt;build&gt; &lt;plugins&gt; &lt;plugin&gt; &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt; &lt;artifactId&gt;maven-war-plugin&lt;/artifactId&gt; &lt;version&gt;2.4&lt;/version&gt; &lt;/plugin&gt; &lt;plugin&gt; &lt;groupId&gt;org.eclipse.jetty&lt;/groupId&gt; &lt;artifactId&gt;jetty-maven-plugin&lt;/artifactId&gt; &lt;version&gt;9.0.4.v20130625&lt;/version&gt; &lt;configuration&gt; &lt;scanIntervalSeconds&gt;30&lt;/scanIntervalSeconds&gt; &lt;webApp&gt; &lt;contextPath&gt;/blabla&lt;/contextPath&gt; &lt;/webApp&gt; &lt;/configuration&gt; &lt;/plugin&gt; &lt;/plugins&gt; &lt;/build&gt; &lt;/project&gt; </code></pre>

    1. COWhat IDE are you using? Some, like Eclipse, have good support for maven and webapps via plugins like [m2e](http://eclipse.org/m2e/) and [WTP](http://projects.eclipse.org/projects/webtools).

    2. COIntelliJ. It is not the lack of support for it in the IDE, but I would think it could be done entirely in maven.

    3. COWhat about the [maven jetty plugin](http://maven.apache.org/plugins/maven-war-plugin/examples/rapid-testing-jetty6-plugin.html) is not suiting your needs? Is it not picking up the updated `target/classes` after a `mvn compile`?

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
