JNI error

[amerolla]

I tried running:
java -cp aircompressor-0.12-SNAPSHOT-tests.jar io.airlift.compress.benchmark.CompressionBenchmark

Got the following error:
Error: A JNI error has occurred, please check your installation and try again

Is there a dependency I need to add to the pom.xml file?

You need to use mvn exec to run run from the CLI so that it adds all the dependencies to the classpath. E.g.:

mvn exec:exec -Dexec.classpathScope=test -Dexec.executable="$JAVA_HOME/bin/java" -Dexec.args="-XX:+UseG1GC -cp %classpath io.airlift.compress.benchmark.CompressionBenchmark -p algorithm=airlift_lz4 -i 20 -wi 20 -f 10"

The options after CompressionBenchmark are standard JMH args, so adjust as necessary to control parameters, warmup/measurement iterations, etc.

Thank you very much Martin, I'm running now.
