Hello,

Finally got around to testing this...

I have built and repackaged a JAR with the following classes:

/usr/lib/flume-ng/lib$ jar tf flume-ng-RegexCaptureInterceptor-1.3.jar
META-INF/
META-INF/MANIFEST.MF
META-INF/DEPENDENCIES
META-INF/LICENSE
META-INF/maven/
META-INF/maven/org.apache.flume/
META-INF/maven/org.apache.flume/flume-ng-core/
META-INF/maven/org.apache.flume/flume-ng-core/pom.properties
META-INF/maven/org.apache.flume/flume-ng-core/pom.xml
META-INF/NOTICE

org/apache/flume/interceptor/RegexExtractorInterceptorMillisSerializer.class
org/apache/flume/interceptor/RegexExtractorInterceptorPassThroughSerializer.class
org/apache/flume/interceptor/RegexExtractorInterceptorSerializer.class

However when trying to start an agent with this setup I get the following errors:

4:55:16.866 PM	ERROR	org.apache.flume.channel.ChannelProcessor	
Could not instantiate Builder. Exception follows.

Any insight as to what's going wrong is appreciated.

Thank you,

Hi,

If you built flume 1.3.0 and took the RegexExtractorInterceptor class files, built your own jar with just these class files, and placed that jar in Flumes classpath you'd be able to specify the fully qualified class name of the RegexExtractorInterceptor.

Too bad we did't make RegexExtractorInterceptor it's own module as it would be easier.
