How to package different JARs based on different classes?

[fluency03]

When I want to deploy the jobs to Flink, I have to submit the each of the job as a JAR.

For example, if I have several different jobs under the module: org.example:

• WordCount
• SocketTextStreamWordCount
• WikipediaEditMonitoring
• etc...

My question is: how to package the jobs to each of their separate JARs, so that I can submit each of the jobs to Fink separately, like:

• WordCount-%version.jar
• SocketTextStreamWordCount-%version.jar
• WikipediaEditMonitoring-%version.jar
• etc...

More specifically, how to configure the build.sbt or set up the sbt project structure?

For example, in the Apache Flink, there is such flink-examples-streaming module and its pom.xml is here: https://github.com/apache/flink/blob/master/flink-examples/flink-examples-streaming/pom.xml .

Inside its pom, there is a maven-jar-plugin, and it has several different executions for each of the example. Inside each execution, its corresponding program-class and included files are specified. Therefore, each execution is going to generate a single JAR file for this individual job.

I would like to know how to do such thing in sbt-assembly.

Many Thanks.

sbt version: 0.13.13

@fluency03 hi，i got the same question too. only find that the mainClass should has a configuration in build.sbt is according to sbt-assemblt-doc

mainClass in assembly := Some("org.example.SocketWordCount"),

a dirty way i got is separating these jars into different project and specify there own mainClass in there project configurations.

have u got any better idea about this question?

thank you very much.

got something in flink-doc about command line usage -c option can specify mainClass, maybe i should package above all into one jar file and specify it on job submitting.
