无法解析项目 org.openjdk.jmh:jmh-core:jar:1.21 的依赖项
Could not resolve dependencies for project org.openjdk.jmh:jmh-core:jar:1.21
想开始做我从现在开始写的方法的基准测试，有很长一段时间的动力，终于决定从昨天开始这样做。但是我对我的设置过程感到震惊。
- 我已经正确安装了 JMH 插件。
- 所有导入工作正常。
- 甚至我的 POM 也没有显示错误。
但是当我 运行 命令 mvn clean install 时，出现以下错误：
[ERROR] Failed to execute goal on project TestOptional: Could not
resolve dependencies for project
Vishwaratna:TestOptional:jar:1.0-SNAPSHOT: The following artifacts
could not be resolve d: org.openjdk.jmh:jmh-core:jar:1.21,
org.openjdk.jmh:jmh-generator-annprocess:jar:1.21: Could not find
artifact org.openjdk.jmh:jmh-core:jar:1.21 in art_all
(http://maven/artifactory/li bs-snapshot)
我想我必须强制更新回购协议，所以我 运行 mvn -U clean install ，还是没有运气。
进行了大量搜索并浏览了 N 个 SO 线程，但仍然无法找出我哪里出错了。
当我 运行 我的 Testing.java class 时，我收到以下消息：
No matching benchmarks. Miss-spelled regexp?
Use EXTRA verbose mode to debug the pattern matching.
Process finished with exit code 1
我很困惑，当 maven 无法从中央代表处找到那些 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？？如果正确导入了库，那么为什么当我从终端 运行 mvn clean install 时收到无法下载 xx 的错误？
经过2个小时的挣扎，我想放弃POM.xml并尝试手动添加jar，我下载了JMH注释jar和JMH核心jar并手动配置了路径。猜猜还是没有运气。
如果你想知道我在编码什么：

我已经成功 运行 你的例子。
我唯一需要更改的是将您的 Testing.java 放入任何包中，例如 package t;
如果你的 repo 有任何问题，如果你的 settings.xml 文件中没有任何奇怪的设置，请尝试。 https://maven.apache.org/settings.html。可能有一些代理集或类似的东西，这可能会改变您对项目的预期行为。
将 settings.xml 中的网址更改为 https://repo1.maven.org/maven2/
对我来说，唯一的解决方案是转到位于 ${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 可以在我执行 clean 和 install 时再次下载这个包。

这表明我没有任何 proxy 问题，现在当我在浏览器中使用任何 JMH link 时，我得到一个json 响应，示例：

我已经成功 运行 你的例子。
我唯一需要更改的是将您的 Testing.java 放入任何包中，例如 package t;
如果你的 repo 有任何问题，如果你的 settings.xml 文件中没有任何奇怪的设置，请尝试。 https://maven.apache.org/settings.html。可能有一些代理集或类似的东西，这可能会改变您对项目的预期行为。
将 settings.xml 中的网址更改为 https://repo1.maven.org/maven2/
对我来说，唯一的解决方案是转到位于 ${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 可以在我执行 clean 和 install 时再次下载这个包。
