Compile for Windows 7, JMeter 3.3 and Kafka 0.11.0.0, NullPointerException when running test plan about pepper-box HOT 6 OPEN

Taking below actions solved my problem:

1. switch to branch: ''jmeter3.2_kafka0.11.0.0"
2. remove unused import such as net.didion.jwnl.data.Exc in all test classes since I could not include the dependency nor download it and it's not used
3. run mvn clean install -Dkafka.version=0.11.0.0 -Djmeter.version=3.3 -DskipTests since it will give NullPointerException when running test class

This way I can build source but not sure if there's impact on the performance.

After adding the jar to JMeter lib/ext and restart, I can see the plug-in items.

Hope you have pulled correct branch as we already have branch for Kafka 0.11 did you tried that?

from pepper-box.

Yes I switched to "jmeter3.2_kafka0.11.0.0".

I was able to build and 2 .jar files were generated: pepper-box-1.0.jar and original-pepper-box-1.0.jar which were both copied under lib/ext of jmeter. But when I run the test plan, it threw error:

And here's JAVA_HOME, Java and Maven version:

$ echo $JAVA_HOME
C:\Program Files\Java\jdk1.8.0_121

$ java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

$ mvn -version
Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-03T15:39:06-04:00)
Maven home: C:\Program Files\apache-maven-3.5.0
Java version: 1.8.0_121, vendor: Oracle Corporation

Default locale: en_US, platform encoding: Cp1252
OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows"

I'm not sure if this is the cause but what I've read is that the exception happens when Java home is pointing to JRE not JDK. But actually my JAVA_HOME env var is set to JDK directory, and Maven will always look for JRE.

First You should not put both jar, remove jar containing name original second jmeter is picking jre instead of jdk, check your PATH variable should not contain jre path

from pepper-box.

I removed original-pepper-box-1.0.jar, and make sure JRE is not in PATH var. In PATH variable, JAVA_HOME is pointing to JDK path, and you can see from Maven Java home: C:\Program Files\Java\jdk1.8.0_121\jre.
The problem is, Maven picks up JRE automatically, because even if I delete the jre folder under JDK path, it will look for jre install path

@satishbhor i am also facing this issue like gslab file cant load getting null pointer error.

kafka version :-kafka_2.11-2.0.0
Apche jmeter:- apache-jmeter-4.0
JDK 1.8 (Set JAVA_HOME till jdk path)

could you provide latest docs so everyone can used that.

Thanks
