Exception when trying to run simple test

[ThePickNick]

Hello I tried to test the driver out but When compiling the source "sbt compile" and try to run it "sbt run" to test I get Java.lang.runtimeExpection: no main class detected

when I package the code and try to run the simple Java app I get error with using the driver

Class.forname("com.github.mmolimar.ksql.jdbc.ksqldriver");

Exception in thread "main" Java.lang.NoClassDefFoundError: scala/ Function1 At java.lang.class.forname0(native method) At java.lang.class.forname(unknown source) ...

Did anyone stumble on similar issue and knows how to overcome it?

Thank you.

Have you tried with java.sql.DriverManager.registerDriver(new com.github.mmolimar.ksql.jdbc.KsqlDriver)?

Getting the same error as ThePickNick; however, I'm getting it out of RazorSQL when trying to use the driver to query my ksql server, any ideas?

Same when using the produced driver jar in Intellij:

Its most likely because the produced jar is not a fat-jar, i.e. is missing the internal dependencies of the driver. Not sure hot to fix that, because it's done in sbt.

@ThePickNick, you may have to add the dependencies to your project. If you are using maven, it would be these two deps:

        <dependency>
            <groupId>org.scala-lang</groupId>
            <artifactId>scala-library</artifactId>
            <version>2.11.11</version>
        </dependency>

        <dependency>
            <groupId>io.confluent.ksql</groupId>
            <artifactId>ksql-rest-app</artifactId>
            <version>4.1.0</version>
        </dependency>

[mmolimar]

Can you try with the new version? Build the jar executing sbt clean assembly.

[holgerbrandl]

I've tried with the fat-version of the current master, and the noclassdef error seems fixed.

Great!
