[xwiki-devs] maven error when trying to write my own component - xwiki-devs@xwiki.org

12 Nov 2010

Hi all,

It's my first time trying to develop my own component per this page: 
http://platform.xwiki.org/xwiki/bin/view/DevGuide/WritingComponents

I ran the maven create component steps as follows:

    C:\dev\xwiki\xwiki-enterprise-2.5-rc-1> mvn install:install-file
    -Dfile="C:/Downloads/xwiki-archetype-component-1.0-SNAPSHOT.jar"
    -DartifactId=xwiki-archetype-component
    -DgroupId=com.xpn.xwiki.platform.tools -Dversion=1.0-SNAPSHOT
    -Dpackaging=jar
    . . .
    C:\dev\xwiki\xwiki-enterprise-2.5-rc-1>mvn archetype:generate
    -DarchetypeGroupId=com.xpn.xwiki.platform.tools
    -DarchetypeArtifactId=xwiki-archetype-component
    -DarchetypeVersion=1.0-SNAPSHOT
    -DgroupId=com.modusoperandi.xwiki.extentions
    -DartifactId=xwiki-marktest  -Dpackage=com.modusoperandi.xwiki.ext
    -Dversion=0.1 -Dpackaging=jar
    . . .

Now I have an xwiki-marktest project.

Had to comment out the "1.8-SNAPSHOT" property value, making my pom.xml 
look like this:

    C:\dev\xwiki\xwiki-enterprise-2.5-rc-1\xwiki-marktest>   type pom.xml
    <?xml version="1.0" encoding="UTF-8"?>
    <!--

    <properties>
    <!-- TODO: remove this if you inherit a project that has the core
    version set

                       -->
    </properties>
    <dependencies>
    <dependency>
    <groupId>org.xwiki.platform</groupId>

    <version>3.8.1</version>
    <scope>test</scope>
    </dependency>
    <!-- Add here all your other dependencies -->
    </dependencies>
    </project>

But when I try to compile I get the "Failure to find..." error shown below.

    C:\dev\xwiki\xwiki-enterprise-2.5-rc-1\xwiki-marktest>mvn compile

What do I do now?? Any help would be greatly appreciated.
