Git命令导致ConnectException

Question

我正试图在我的机器上安装并运行以下项目：

https://github.com/spring-petclinic/spring-petclinic-angularjs.git

我一步一步地做每一件事，但与以下命令作斗争：

./mvnw clean install

在这里，我得到了以下错误消息(有关我的设置的更多细节，请参见下面的消息)：

我支持一个公司代理，但是我的系统上的一切都应该被正确地配置为使用它：

Eclipse具有设置，Maven在ist Settings.xml中有设置，在Git中也有设置，我使用以下方法配置了代理：

git config --global http.proxy [MYPROXY]:[PORT]
git config --global https.proxy [MYPROXY]:[PORT]

Answer 1

同时，我通过手动安装Apache 3.3.3并将安装路径bin-目录放入我的PATH-windows系统环境变量中，“解决了”这个问题。另外，我没有执行mvnw命令，而是执行mvn命令。

./mvn clean install

它可以工作，但它是一个快速和简单的解决办法，而不是一个解决方案。

Answer 2

通过更改以下行，在mvnw.cmd中添加代理设置，解决了同样的问题：

%MAVEN_JAVA_EXE% %JVM_CONFIG_MAVEN_PROPS% %MAVEN_OPTS% %MAVEN_DEBUG_OPTS% -classpath %WRAPPER_JAR% "-Dmaven.multiModuleProjectDirectory=%MAVEN_PROJECTBASEDIR%" %WRAPPER_LAUNCHER% %MAVEN_CONFIG% %*

至

%MAVEN_JAVA_EXE% %JVM_CONFIG_MAVEN_PROPS% %MAVEN_OPTS% %MAVEN_DEBUG_OPTS% -classpath %WRAPPER_JAR% "-Dmaven.multiModuleProjectDirectory=%MAVEN_PROJECTBASEDIR%" "-Dhttp.proxyHost=myProxyServer" "-Dhttp.proxyPort=8080" "-Dhttps.proxyHost=myProxyServer" "-Dhttps.proxyPort=8080" %WRAPPER_LAUNCHER% %MAVEN_CONFIG% %*
