I receive this error when I try to run the maven goal – mvn eclipse:eclipse -Dwtpversion=3.3.1

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-eclipse-plugin:2.8
:eclipse (default-cli) on project conference-web: Unsupported WTP version: 3.3.1
. This plugin currently supports only the following versions: 1.0 1.5 2.0 R7 non
e. -> [Help 1]
[ERROR]

Will using version 2.0 suffice ? But should’nt the goal run successfully ?

<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-eclipse-plugin</artifactId>
<configuration>
    <wtpmanifest>true</wtpmanifest>
    <wtpapplicationxml>true</wtpapplicationxml>
    <wtpversion>2.0</wtpversion>
</configuration>

Does’nt below image confirm I am use wtp version 3.3.1 ?

    you can use the latest supported wtp version of the plugin, open the project in eclipse and in the ‘problems’ view right click on the warning “wtp project version to old” and choose ‘quickfix.

    As far as i remember the support of wtp was removed from the plugin since the maven eclipse m2eclipse plugin got more advanced. Any reasons you’re not using that one?
