JMH无法找到资源：/ META-INF / BenchmarkList [英] JMH Unable to find the resource: /META-INF/BenchmarkList

问题描述

我不能在eclipse中运行简单的JMH基准。
Maven依赖关系：

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

Java代码

  public class BTest {
 @Benchmark 
 public void test（）{
 // todo 
} 
 
 public static void main（String [] args）throws RunnerException {
选项opt = new OptionsBuilder（）
 .include（BTest.class.getSimpleName（））
 .build（） ; 
 
 new Runner（opt）.run（）; 
} 
} 
  

运行结果

线程main中的异常java.lang.RuntimeException：ERROR：Unable
查找资源：/ META-INF / BenchmarkList
org.openjdk.jmh.runner.AbstractResourceReader.getReaders（AbstractResourceReader.java:96）
在org.openjdk.jmh.runner.BenchmarkList.find（BenchmarkList.java:104）
在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）

也许问题是，我从eclipse运行它。

感谢任何帮助。

解决方案

终于找到了。
有一个问题，缺少 exec-maven-plugin 插件

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.

Thanks for any help.

解决方案

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>
