You can build plugin and run jmeter with it, by running maven command:
mvn package antrun:run -Djmeter.executable=<full path to jmeter executable file>
Latest Jmeter release (2.11) has issue in the code (JMeter.java). They trying to parse search_paths value with ';' instead of using system path.separator variable. That is why we are replacing all ':' with ';' in ant task before run jmeter:
<loadresource property="runtime_classpath_fixed">
<propertyresource name="runtime_classpath"/>
<filterchain>
<tokenfilter>
<filetokenizer/>
<replacestring from=":" to=";"/>
</tokenfilter>
</filterchain>
</loadresource>
