There is no need to build or compile plugin from eclipse.If you use ant-build for build openfire then it work fine. Just you make sure, Ant is installed and configure proper path in your system.

Go to your downloaded openfire and paste your plugin under openfire/src/plugin folder.

Go command line, you can pass command

ant -f build/build.xml clean openfire plugins

or build specific plugin you can pass

ant -f build/build.xml clean openfire plugin -Dplugin=nameofyourplugin

after building you can check your plugin in this path.

\openfire\target\openfire\plugins

Thanks hope this will help you.

According to our extended discussion from chat, you added the following part:

<condition property="java.not.ok" value="true"> 
    <not> 
        <or> 
            <contains string="${ant.java.version}" substring="1.5"/> 
            <contains string="${ant.java.version}" substring="1.6"/> 
            <contains string="${ant.java.version}" substring="1.7"/> 
        </or> 
    </not> 
</condition> 

You also need to add the following line after those 3 similar lines:

            <contains string="${ant.java.version}" substring="1.8"/> 

because you are using Java 8 (according to your comment related to compiler version). Otherwise, this condition will be evaluated to true (java.not.ok=true) and this will activate the following line:

<fail if="java.not.ok" message="Must use JDK 1.5.x or higher to build Openfire"/>
