Netbeans doesn't recognize xercesimpl

问题

I am trying to build a plugin for netbeans using maven and for some reason Netbeans doesn't recognize xercesimpl.jar packaged with the plugin. Here is the stacktrace I see.

java.io.IOException: SAX2 driver class org.apache.xerces.parsers.SAXParser not found

Here is the image showing that the xercesimpl.jar is indeed packaged with the nbm file.

Here is a list of all the jars that were downloaded during build process.

I am not sure what I am missing, any help is appreciated.

My dependencies weren't right, so once I fixed them, it started recognizing. For anybody looking to include Batik in their maven based netbeans module I am including the dependencies below.

    <dependency>
        <groupId>batik</groupId>
        <artifactId>batik-swing</artifactId>
        <version>1.6-1</version>
        <type>jar</type>
    </dependency>
    <dependency>
        <groupId>batik</groupId>
        <artifactId>batik-script</artifactId>
        <version>1.6-1</version>
        <!-- exclude xerces as Netbeans includes it -->
        <exclusions>
            <exclusion>
                <groupId>xerces</groupId>
                <artifactId>xercesImpl</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <!-- include xerces in test scope as unittests need it -->
    <dependency>
        <groupId>xerces</groupId>
        <artifactId>xercesImpl</artifactId>
        <version>2.5.0</version>
        <type>jar</type>
        <scope>test</scope>
    </dependency>
