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


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.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.


Solution

  • 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>
        <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>
