Question

我正在尝试在anypoint studio中使用maven构建一个新项目。但是，我收到以下错误：

在首选项中，我将“已安装的JRE”设置为指向JDK安装（JDK1.8.0_131）。我正在使用的maven版本是3.5.0。

POM配置如下（仅包括错误中的相关部分）：

<modelVersion>4.0.0</modelVersion>
<groupId>com.mycompany</groupId>
<artifactId>soap_wsclient_maven</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>mule</packaging>
<name>Mule soap_wsclient_maven Application</name>
....
 <plugin>
            <groupId>org.mule.tools.maven</groupId>
            <artifactId>mule-app-maven-plugin</artifactId>
            <version>${mule.tools.version}</version>
            <extensions>true</extensions>
            <configuration>
                <copyToAppsDirectory>true</copyToAppsDirectory>
            </configuration>
  </plugin>

P.S。我知道这个问题已被问过好几次了。但我无法解决我审查类似问题的问题。

显然这是代理问题。所以我通过在maven中的settings.xml上添加代理配置解决了这个问题：

 <proxy>
  <id>optional</id>
  <active>true</active>
  <protocol>http</protocol>
  <username>proxyuser</username>
  <password>proxypass</password>
  <host>proxy.host.net</host>
  <port>80</port>
  <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
</proxy>
