Maven + Spring Boot：在类路径中发现了多次org.json.JSONObject：

spring-boot

我跑步时mvn test收到此警告。我该如何解决？

Found multiple occurrences of org.json.JSONObject on the class path:

        jar:file:/C:/Users/Chloe/.m2/repository/org/json/json/20140107/json-20140107.jar!/org/json/JSONObject.class
        jar:file:/C:/Users/Chloe/.m2/repository/com/vaadin/external/google/android-json/0.0.20131108.vaadin1/android-json-0.0.20131108.vaadin1.jar!/org/json/JSONObject.class

You may wish to exclude one of them to ensure predictable runtime behavior

这是我的pom.xml。对JSON的唯一引用是

    <!-- https://mvnrepository.com/artifact/org.json/json -->
    <dependency>
        <groupId>org.json</groupId>
        <artifactId>json</artifactId>
    </dependency>

Apache Maven 3.5.3

添加下

 <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>

以下排除：

 <scope>test</scope>
    <exclusions>
        <exclusion>
            <groupId>com.vaadin.external.google</groupId>
            <artifactId>android-json</artifactId>
        </exclusion>
    </exclusions>

同样，对于Gradle项目：

testCompile("org.springframework.boot:spring-boot-starter-test") {
    exclude group: "com.vaadin.external.google", module:"android-json"
}
