Maven 使用“mvn install”命令构建失败

Question

我试图为 Cucumber-Maven 报告生成和测试我的代码（如果有效），然后打开命令提示符。我试过“mvn clean”，它是建立成功的。之后，我尝试了“mvn install”并遇到了BUILD FAILURE（显示错误）。[INFO] ------------------------------------------------------------------------[INFO] BUILD FAILURE[INFO] ------------------------------------------------------------------------[INFO] Total time:  22.844 s[INFO] Finished at: 2019-02-05T13:14:51+08:00[INFO] ------------------------------------------------------------------------[ERROR] Plugin org.apache.maven.plugins:maven-surefire-plugin:2.20 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-surefire-plugin:jar:2.20: Could not transfer artifact org.apache.maven.plugins:maven-surefire-plugin:pom:2.20 from/to central (https://repo.maven.apache.org/maven2): Connect to webproxy.sample.com:8080 [webproxy.sample.com/205.165.7.13] failed: Connection timed out: connect -> [Help 1][ERROR][ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.[ERROR] Re-run Maven using the -X switch to enable full debug logging.[ERROR][ERROR] For more information about the errors and possible solutions, please read the following articles:[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/PluginResolutionException

Answer 1

我尝试使用日食。我对同一个 POM 文件使用了 maven clean 和 install 。它工作正常。

C:\users\youruser\.m2\settings.xml看来你的文件有问题。可能是阻止 maven 下载依赖项的代理问题。请检查您的 settings.xml 文件。

Answer 2

它看起来像代理问题，它阻止了依赖项的下载，所以settings.xml如果不存在，请进行一些更改或创建一个。

去c:\users\youruser\.m2\settings.xml.

<?xml version="1.0" encoding="UTF-8"?>
