Answer 1

在您的任何工作室中转到 windows >> 首选项 >> 在左侧菜单中选择java >> 安装的 jre 将其更改为 jdk 路径

Answer 2

我解决了这个问题，我不知道究竟是什么工作，但我更改了 java 版本，并且对于每个项目我执行以下命令：

mvn clean install
mvn eclipse:eclipse

然后我刷新我的项目这可以帮助：http ://www.avajava.com/tutorials/lessons/how-do-i-update-my-maven-project-to-work-in-eclipse.html

Answer 3

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来解决。这解决了我的问题。

Answer 4

我遇到了同样的错误，我不仅通过在已安装的 JRE 中添加 JDK 而是将 JAVASE-1.8 的执行环境设置为 jdk1.8 来解决它，并且它有效。 在此处输入图像描述

您需要为插件添加 Maven 依赖项

第 1 步：编辑 settings.xml 以添加具有以下存储库和 pluginRepositories 的新配置文件。（settings.xml 文件可能存在两个位置：$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>

第二步：添加一个新的pluginGroup，如下图。

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

Answer 6

检查您的MuleStudio.ini是否包含 JDK 正确路径的配置：

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

Answer 7

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>

Answer 8

如果您在使用 Maven 构建项目时遇到来自 Anypoint Studio 的以下错误。

[ERROR] [ERROR] Some problems were encountered while processing the POMs:

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. 这里将 JRE (C:\Program Files\Java\jre1.8.0_162) 更改为您的 JDK (C:\Program Files\Java\jdk1.8.0_162) 并选中 JDK 复选框并单击 Finish -> ok -> ok。

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。

如果您仍然遇到问题，请按照以下步骤操作：

1. 转到 Windows -> 首选项 -> 已安装的 JRE -> 执行环境 这里选择 JavaSE-1.8 并在右侧窗口中单击 jdk1.8.0_162 [完美匹配]，现在尝试更新项目依赖项。

这将解决问题。

我认为这是您的 mule studio Java 设置的问题。Mule studio 默认点 JRE 而不是 JDK。tools.jar 在 JDK 文件夹下可用。请参阅下面的链接，该链接告诉您如何将 JDK 添加到工作室，然后使用它来构建
