JMH Impossibile trovare la risorsa:/META-INF/BenchmarkList

Question

Non riesco a eseguire un semplice benchmark JMH all'interno di eclipse. Maven Dipendenze:

 <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> 

codice Java:

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(); 
    } 
} 

Risultato di periodo:

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)

Forse il problema è che sto correndo da Eclipse.

Grazie per qualsiasi aiuto.

Finalmente scoperto. C'è stato un problema con mancante exec-maven-plugin plug

<plugin> 
    <groupId>org.codehaus.mojo</groupId> 
    <artifactId>exec-maven-plugin</artifactId> 
    <executions> 
     <execution> 
      <id>run-benchmarks</id> 
      <phase>integration-test</phase> 
      <goals> 
       <goal>exec</goal> 
      </goals> 
      <configuration> 
       <classpathScope>test</classpathScope> 
       <executable>java</executable> 
       <arguments> 
        <argument>-classpath</argument> 
        <classpath /> 
        <argument>org.openjdk.jmh.Main</argument> 
        <argument>.*</argument> 
       </arguments> 
      </configuration> 
     </execution> 
    </executions> 
</plugin>
