Question

我使用snakeyml读取yml文件并将其加载到Java对象中。

问题：当我执行Yaml yml = new Yaml()时，会创建yml实例。但是当我传递构造函数参数时，不会创建yml实例。我也没有看到异常。这是完整的代码。

private static YamlConfig readStatsConfig()
        throws IOException {

    InputStream input = new FileInputStream(new File(configFile));
    Constructor constructor = new Constructor(YamlConfig.class);

    TypeDescription description = new TypeDescription(YamlConfig.class);
    description.putListPropertyType("resources", YamlConfig.Resource.class);
    constructor.addTypeDescription(description);

    TypeDescription description = new TypeDescription(
                    YamlConfig.Resource.class);
    description.putListPropertyType("stats", YamlConfig.StatsInfo.class);
    constructor.addTypeDescription(description);

    Yaml yaml = new Yaml(constructor);

    YamlConfig cfg = (YamlConfig) yaml.load(input);

    mainLogger.info(cfg);

    return cfg;
}

以下声明中的代码退出：

Yaml yaml = new Yaml(constructor);

I fixed the issue by excluding snakeyml dependency in TestNG JARs. All we need to do is to add the following in the project POM has dependency with TestNG.

<dependency>
            <groupId>org.testng</groupId>
            <artifactId>testng</artifactId>
            <version>6.3.1</version>
             <type>jar</type>
            <exclusions>
                <exclusion>
                    <artifactId>snakeyaml</artifactId>
                    <groupId>org.yaml</groupId>
                </exclusion>
            </exclusions>
        </dependency>

传递构造函数参数时未创建Yaml实例
