Using Eclipse WTP with Maven's eclipse:eclipse Goal
If you use Maven's "eclipse:eclipse" goal to generate a project descriptor for eclipse, by default you're just going to get a plain Java project. You'll have to add in the Dynamic Web facet in order to tell Eclipse that you can deploy this project in a web container. The easy way around this is to configure the maven-eclipse-plugin in the pom.xml file like this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-eclipse-plugin</artifactId>
<version>2.8</version>
<configuration>
<wtpContextName>some/url/context</wtpContextName>
<wtpversion>1.5</wtpversion>
</configuration>
</plugin>Also, I like to download sources and Javadoc, which makes navigating in Eclipse a lot easier. This can be done like this.
<plugin>
...
<configuration>
<downloadSources>true</downloadSources>
<downloadJavadocs>true</downloadJavadocs>
</configuration>
</plugin>Supposing you also want your project to have JPA facets, or other additional project facets you could also add them in like this
<plugin>
...
<configuration>
<additionalProjectFacets>
<jpt.jpa>2.0</jpt.jpa>
</additionalProjectFacets>
</configuration>
</plugin>And all of these can be combined to do this
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-eclipse-plugin</artifactId>
<version>2.8</version>
<configuration>
<wtpContextName>list</wtpContextName>
<wtpversion>1.5</wtpversion>
<downloadSources>true</downloadSources>
<downloadJavadocs>true</downloadJavadocs>
<additionalProjectFacets>
<jpt.jpa>2.0</jpt.jpa>
</additionalProjectFacets>
</configuration>
</plugin>
