SAXParseException：找不到元素'definitions'的声明

我对camunda和DMN都很陌生 . 我试图在spring-boot中运行DMN示例 . Here is the link例如我想在我的机器上运行 .

这是我的pom依赖项，

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <java.version>1.8</java.version>
    <camunda.version>7.4.0</camunda.version>
</properties>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>

    </dependency>

    <!-- camunda DMN Engine -->
    <dependency>
        <groupId>org.camunda.bpm.dmn</groupId>
        <artifactId>camunda-engine-dmn-bom</artifactId>
        <version>${camunda.version}</version>
        <type>pom</type>
        <scope>import</scope>
    </dependency>

    <dependency>

        <artifactId>camunda-engine-dmn</artifactId>
        <version>${camunda.version}</version>
    </dependency>
</dependencies>

当我运行它时显示以下stacktrace

我没有得到的一件事是，在资源中他们在xml文件中有决策模式，并且他们有xsd的URL无法正常工作 .

经过一些;）研究后我找到了this链接，其中给出了xsd url我尝试了但是再次命名空间url不起作用 .

如果我错过了什么，请做评论:)
