我正在尝试按照本教程https://docs.mulesoft.com/mule-user-guide/v/3.7/building-a-mule-application-with-maven-in-studio创建maven项目，那时Studio自动构建Maven项目，我收到此错误：updating maven project has encountered a problem There was an error running the studio:studio goal on project test并在控制台中：

我解决了这个问题，我不确切知道什么有效但我更改了java版本，并且每个项目都执行以下命令：

mvn clean install
mvn eclipse:eclipse

然后我刷新我的项目 这有助于：http://www.avajava.com/tutorials/lessons/how-do-i-update-my-maven-project-to-work-in-eclipse.html

我遇到了同样的问题，并通过在首选项中将JRE更改为JDK并重新启动任何点工作室得到解决。 这解决了我的问题。

答案 3 :(得分：2)

我遇到了同样的错误，我解决了这个问题，不仅仅是在已安装的JRE中添加JDK，而是将JAVASE-1.8的执行环境设置为jdk1.8并且工作正常。 enter image description here

检查 MuleStudio.ini 是否包含JDK正确路径的配置：

-vm
C:\Path\To\Your\JDK\bin\javaw

您需要为插件添加Maven依赖项

步骤1：编辑settings.xml以使用以下存储库和pluginRepositories添加新配置文件。 （settings.xml文件可以存在两个位置：$ M2_HOME / conf / settings.xml或$ {user.home} /.m2 / settings.xml）

<profiles>
     ...
     <profile>
        <id>mule-extra-repos</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <repositories>
            <repository>
                <id>mule-public</id>
                <url> https://repository.mulesoft.org/nexus/content/repositories/public </url>
            </repository>
        </repositories>
        <pluginRepositories>
            <pluginRepository>
                <id>mule-public</id>
                <url> https://repository.mulesoft.org/nexus/content/repositories/public </url>
            </pluginRepository>
        </pluginRepositories>
     </profile>
     ...
 </profiles>

步骤2：添加一个新的pluginGroup，如下所示。

<pluginGroups>
    ...
    <pluginGroup>org.mule.tools</pluginGroup>
    ...
 </pluginGroups>

我认为这是你的mule studio Java设置的问题。 Mule工作室默认指向JRE而不是JDK。 tools.jar在JDK文件夹下可用。请参阅以下链接，该链接告诉您如何将JDK添加到studio然后使用它来构建

我注意到如果您的流程涉及API Kit和Dataweave，则需要添加其他依赖项。 

        <plugin>
            <executions>
                <execution>
                    <configuration>
                        <resources>
                            <resource>
                                <directory>src/main/api/</directory>
                            </resource>
                        </resources>
                    </configuration>
                </execution>
            </executions>
        </plugin>

和

    <dependency>
        <groupId>org.mule.modules</groupId>
        <artifactId>mule-module-apikit</artifactId>
        <version>${mule.version}</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>com.mulesoft.weave</groupId>
        <artifactId>mule-plugin-weave_2.11</artifactId>
        <version>${mule.version}</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.mule.modules</groupId>
        <artifactId>mule-module-http</artifactId>
        <version>${mule.version}</version>
        <scope>provided</scope>
    </dependency>

如果在使用Maven构建项目时遇到Anypoint Studio的以下错误。 

[ERROR] [ERROR] Some problems were encountered while processing the POMs:
[ERROR] Unresolveable build extension: Plugin org.mule.tools.maven:mule-app-maven-plugin:1.2 or one of its dependencies could not be resolved: Could not find artifact com.sun:tools:jar:1.5.0 at specified path C:\Program Files\Java\jre1.8.0_162/../lib/tools.jar @

请按照以下步骤解决问题

  1. 从Anypoint studio转到Windows->首选项->已安装的JRE。
  2. 在此将JRE（C：\ Program Files \ Java \ jre1.8.0_162）更改为JDK（C：\ Program Files \ Java \ jdk1.8.0_162）并选择JDK复选框，然后单击Finish-> ok- >好的。

现在尝试通过右键单击pom.xml文件Mule->更新项目依赖项来更新pom.xml文件。

如果仍然遇到问题，请执行以下另一步骤：

  1. 转到Windows->首选项->已安装的JRE->执行环境 在这里选择JavaSE-1.8，然后在右窗口上单击jdk1.8.0_162 [完全匹配] 然后尝试更新项目依赖项。

这将解决问题。
