Answer 1

Just add a new folder "java" under src/main. will solve the problem. Because the classpath with java folder is already available in .classpath file of created project, so adding java folder will not cause any error. see below entry in .classpath file, which allows to add java folder.

<attributes>
<attribute name="optional" value="true"/>
<attribute name="maven.pomderived" value="true"/>

Here is my solution. It works without any issue.

There could be questions regarding why all this steps are required and i believe they are pretty genuine. But this is one of the ways to make your web application or any other component working on eclipse using Maven from command line.

1) Open a command window

2) mvn archetype:generate -DgroupId=your package -DartifactId=your Project -DarchetypeArtifactId= your archetype. In my case "maven-archetype-webapp" -DinteractiveMode=false

3) cd your Project

4) mvn eclipse:eclipse -Dwtpversion=2.0

5) Go to file system. Go to your newly created project. create folders, a) java under main
b) test under src c) java and resources under test

6) mvn eclipse:clean

7) mvn eclipse:eclipse -Dwtpversion=2.0

8) import your Project project in eclipse

Answer 4

1. By default, When you create a project with maven archetype "maven-archetype-webapp", it doesn't create any java and test folders.
2. You can manually add those folders as src/main/java and src/test/java.
3. After adding these folders, right click on your project in project explorer, go to maven>update project conf.

Answer 5

Simply create new folder named java under src/main/

Then right click on project and select maven->update project

Answer 6

error occurs when the JRE System Library is wrongly pointed. Now go to Libraries tab and change the JRE System Library to the correct version.
