JMH Unable to find the resource: /META-INF/BenchmarkList

Question

I'm not able to run simple JMH benchmark inside eclipse. Maven dependencies:

        <dependency>
            <groupId>org.openjdk.jmh</groupId>
            <artifactId>jmh-core</artifactId>
            <version>1.12</version>
        </dependency>
        <dependency>
            <groupId>org.openjdk.jmh</groupId>
            <artifactId>jmh-generator-annprocess</artifactId>
            <version>1.12</version>
        </dependency>

Java code:

public class BTest {
    @Benchmark
    public void test() {
        // todo
    }

    public static void main(String[] args) throws RunnerException {
        Options opt = new OptionsBuilder()
                 .include(BTest.class.getSimpleName())
                  .build();

        new Runner(opt).run();
    }
}

Result of run:

Exception in thread "main" java.lang.RuntimeException: ERROR: Unable to find the resource: /META-INF/BenchmarkList at org.openjdk.jmh.runner.AbstractResourceReader.getReaders(AbstractResourceReader.java:96) at org.openjdk.jmh.runner.BenchmarkList.find(BenchmarkList.java:104) at org.openjdk.jmh.runner.Runner.internalRun(Runner.java:256) at org.openjdk.jmh.runner.Runner.run(Runner.java:206) at com.test.BTest.main(BTest.java:24)

Maybe the problem is, that I'm running it from eclipse.

Finally found it out. There was a problem with missing exec-maven-plugin plugin

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>

        </execution>
    </executions>
</plugin>
