Mule Anypoint Studio groovy.lang.MissingPropertyException:没有此类属性：类的StringEscapeUtils

这是针对4.3 EE运行时上的Mule 4的

更新 POM文件具有标准依赖关系，多亏了Aled的回答，还将其作为共享库包括在内：

电话本身完全失败了：

StringEscapeUtils.escapeCsv(csvText);

实际误差：

因为您需要将Apache Commons Lang3库标记为pom中的，所以脚本模块可以看到它：

        <plugin>
            <groupId>org.mule.tools.maven</groupId>
            <artifactId>mule-maven-plugin</artifactId>
            <version>${mule.maven.plugin.version}</version>
            <extensions>true</extensions>
            <configuration>
                <sharedLibraries>
                    <sharedLibrary> <!-- make commons-lang3 shared -->
                        <groupId>org.apache.commons</groupId>
                        <artifactId>commons-lang3</artifactId>
                    </sharedLibrary>
                  </sharedLibraries>
            </configuration>
        </plugin>

org.mule.tools.maven
mule maven插件
${mule.maven.plugin.version}
真的
org.apache.commons
commons-lang3

感谢您的洞察力。我应该补充一点，这也需要作为一个标准依赖项添加，否则它将无法编译，令人沮丧的是，它没有给出真正的解释。我将更新原始问题。正确的解决方案-我的错误是将导入实现为lang而不是lang3。这就是当你测试某个东西而忘记将其恢复到原始值时发生的情况。在所有类型的测试之后，我将lang3更改为lang，这导致了第二个问题。亚历德的解决方案是正确的，并将其标记为正确的。

StringEscapeUtils.escapeCsv(csvText);
