如何将 Apache Beam 直接运行器添加到类路径？

Question

我正在尝试对 Apache Beam 的 MinimalWordCount 示例项目进行简单的衍生。 我开始了一个新项目，而不是下载他们的原型。 我遇到了一个明显常见的问题，通用解决方案没有解决这个问题：

Exception in thread "main" java.lang.IllegalArgumentException: No Runner was specified and the DirectRunner was not found on the classpath.
Specify a runner by either:
    Explicitly specifying a runner by providing the 'runner' property
    Adding the DirectRunner to the classpath
    Calling 'PipelineOptions.setRunner(PipelineRunner)' directly

SO 上的常见解决方案是添加正确的依赖项，我已经完成了。 这是我非常简单的 POM：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.example</groupId>
    <artifactId>test_pipeline</artifactId>
    <version>1.0-SNAPSHOT</version>

    <properties>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
    </properties>

    <dependencies>
        <!-- https://mvnrepository.com/artifact/org.apache.beam/beam-runners-direct-java -->
        <dependency>
            <groupId>org.apache.beam</groupId>
            <artifactId>beam-runners-direct-java</artifactId>
            <version>2.33.0</version>
            <scope>test</scope>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.apache.beam/beam-sdks-java-core -->
        <dependency>
            <groupId>org.apache.beam</groupId>
            <artifactId>beam-sdks-java-core</artifactId>
            <version>2.33.0</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.apache.beam/beam-sdks-java-extensions-json-jackson -->
        <dependency>
            <groupId>org.apache.beam</groupId>
            <artifactId>beam-sdks-java-extensions-json-jackson</artifactId>
            <version>2.33.0</version>
        </dependency>
    </dependencies>
</project>

那么如何将直接运行程序添加到我的类路径中（或以任何其他方式解决此问题）？

Answer 1

尝试删除

<scope>test</scope>

来自beam-runners-direct-java依赖项。
