Mule / Maven Error: Invalid content was found starting with element 'dw:transform-message'

Question

我正在尝试运行使用 Maven 的项目，使用简单的测试 class，但是测试出错（没有失败！）并显示消息：

Test set: com.mycompany.myproject.testApiResponseNotNullTestCase

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 4.423 sec <<< FAILURE! - in com.mycompany.myproject.testApiResponseNotNullTestCase clientTestCase(com.mycompany.myproject.testApiResponseNotNullTestCase) Time elapsed: 3.084 sec <<< ERROR! org.mule.api.config.ConfigurationException: Line 34 in XML document from URL [file:/C:/Users/myuser/Documents/.../dev/Mule%20Workspaces/myproject/myproject/target/test-classes/myproject.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 34; columnNumber: 111; cvc-complex-type.2.4.a: Invalid content was found starting with element 'dw:transform-message'. One of '{"http://www.mulesoft.org/schema/mule/core":abstract-message-processor, "http://www.mulesoft.org/schema/mule/core":abstract-outbound-endpoint, "http://www.mulesoft.org/schema/mule/core":abstract-mixed-content-message-processor, "http://www.mulesoft.org/schema/mule/core":response, "http://www.mulesoft.org/schema/mule/core":legacy-abstract-exception-strategy, "http://www.mulesoft.org/schema/mule/core":abstract-message-info-mapping}' is expected. (org.mule.api.lifecycle.InitialisationException) Caused by: org.mule.api.lifecycle.InitialisationException: Line 34 in XML document from URL [file:/C:/Users/myuser/Documents/.../dev/Mule%20Workspaces/myproject/myproject/target/test-classes/myproject.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 34; columnNumber: 111; cvc-complex-type.2.4.a: Invalid content was found starting with element 'dw:transform-message'.

我已经尝试通过将以下内容添加到我的pom.xml

来解决这个问题

<dependency>
   <groupId>com.mulesoft.weave</groupId>
   <artifactId>mule-plugin-weave</artifactId>
   <version>4.0.0-M4</version>
</dependency>

"expected" 之后提到的所有其他项目都出现在模式中，而 dw:transform-message 没有出现，这似乎很奇怪（或者可能完全符合预期！？）...但这是 XML 由 Anypoint Studio AFAIK 生成。

Answer 1

org/xml/sax/SAXParseException.html 基本上意味着您项目的 XML 文档中缺少信息。

This exception may include information for locating the error in the original XML document, as if it came from a Locator object. Note that although the application will receive a SAXParseException as the argument to the handlers in the ErrorHandler interface, the application is not actually required to throw the exception; instead, it can simply read the information in it and take a different action

并且错误堆栈跟踪清楚地表明在你的情况下它

Caused by: org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'dw:transform-message'

需要固定在

Line 34 in XML document from URL [file:/C:/Users/myuser/Documents/.../dev/Mule%20Workspaces/myproject/myproject/target/test-classes/myproject.xml]

Answer 2

在您的 pom 中添加此依赖项

 <dependency>
        <groupId>com.mulesoft.weave</groupId>
        <artifactId>mule-plugin-weave_2.11</artifactId>
        <version>${mule-version}</version>
</dependency>

Answer 3

您必须添加与您的 Mule Runtime 版本匹配的确切版本。如果你的版本在 3.7.0 和 3.8.1 之间你需要添加：

<dependency>
        <groupId>com.mulesoft.weave</groupId>
        <artifactId>mule-plugin-weave_2.11</artifactId>
        <version>${mule-version}</version>
</dependency>

如果大于3.8.1小于4:

<dependency>
        <groupId>com.mulesoft.weave</groupId>
        <artifactId>mule-plugin-weave</artifactId>
        <version>${mule-version}</version>
</dependency>

对于 4.0.0+ 你不应该添加任何东西。

您不得添加与运行时版本不同的版本。您不是这样做来升级 DataWeave，它会导致未定义和不受支持的行为。
