I modified maven script to include
org.apache.sling.commons.classloader-1.2.2.jar in classpath.
exec "$JAVACMD" \
$MAVEN_OPTS \
-classpath
"${HOME}/.m2/repository/org/apache/sling/org.apache.sling.commons.classloader/1.2.2/org.apache.sling.commons.classloader-1.2.2.jar:${M2_HOME}/boot/classworlds-1.1.jar"
\
"-Dclassworlds.conf=${M2_HOME}/bin/m2.conf" \
"-Dmaven.home=${M2_HOME}" \
${CLASSWORLDS_LAUNCHER} $QUOTED_ARGS
Then jspc works without complaining.
Why would jspc use org.apache.sling.commons.classloader.DynamicClassLoader
?
Why would DynamicClassLoader have to be added to jvm's classpath ?
