无法解决项目org.openjdk.jmh:jmh:jar:1.21的依赖关系

Question

想要开始做方法的基准测试，从现在开始写，从很长一段时间就有了动力，最后决定从昨天开始做。但我对我的设置过程很感兴趣。

• 我已经正确安装了JMH插件。
• 所有进口产品都正常工作。
• 即使是我的POM也没有显示错误。

但是，当我运行命令mvn clean install时，我得到以下错误：

未能执行项目TestOptional:无法解决项目Vishwaratna的依赖关系:TestOptional:jar:1.0-快照:下列工件无法解析d: jmh-core:jmh:1.21，org.openjdk.jmh:jmh-generator-annprocess:jar:1.21:找不到art_all中的工件org.openjdk.jmh:jmh-core:jar:1.21 (http://maven/artifactory/li bs-快照)

我想我必须强制更新repos，所以我运行了mvn -U clean install，再次没有运气。

做了大量的搜索，检查了N个SO线程，但仍然找不出我哪里出错了。

当我只运行我的Testing.java类时，我得到以下消息：

没有匹配的基准。小姐-拼写为regexp? 使用额外的详细模式来调试模式匹配. 进程已完成，退出代码为%1

我感到困惑的是，当maven无法从中央代表中找到那些JMH库时，为什么我的带有所有注释的代码没有显示红色编译错误呢？如果lib导入正确，那么为什么当我从终端运行mvn clean install时不能下载xx的错误呢？

经过两个小时的挣扎，我想放弃POM.xml，尝试手动添加jar，下载JMH注释jar和JMH核心jar并手动配置路径。猜猜还有什么不走运的。

如果你想知道我在编码什么：

import org.openjdk.jmh.annotations.Benchmark;
import org.openjdk.jmh.annotations.BenchmarkMode;
import org.openjdk.jmh.annotations.Mode;
import org.openjdk.jmh.runner.Runner;
import org.openjdk.jmh.runner.RunnerException;
import org.openjdk.jmh.runner.options.Options;
import org.openjdk.jmh.runner.options.OptionsBuilder;

public class Testing {
    @Benchmark
    @BenchmarkMode({ Mode.AverageTime})
    public void wellHelloThere() {
        // this method was intentionally left blank.
    }
    public static void main(String[] args) throws RunnerException {
        Options opt = new OptionsBuilder()
            .include(Testing.class.getSimpleName())
            .forks(1)
            .build();

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

通过命令mvn -U clean install，我不得不更新repos，并获得了这些下载。

Answer 1

我已经成功地运行了你的例子。我唯一需要改变的就是把你的Testing.java放到任何包中，例如package t;。

如果您的回购有任何问题，请尝试如果您没有任何奇怪的设置在您的settings.xml文件。https://maven.apache.org/settings.html。可能有一些提前设定或类似的东西，这可能会改变您预期的行为，您的项目。

将settings.xml中的URL更改为https://repo1.maven.org/maven2/

Answer 2

对我来说，唯一的解决方案是访问${user.home}/.m2/的本地maven存储库并删除jmh包。

rm -Rf ${user.home}/.m2/repository/org/openjdk/jmh*

然后，IntelliJ可以再次下载这个包，当我做clean和install时。
