是否有人使用本地maven repo中的snakeyaml成功加载了yaml文件?

如果我引用 SnakeYAML 直接从一个测试程序(见底部)JAR,一切正常。如果我在Maven创建的项目中,我将从单元测试中获得以下输出:

java.lang.NoSuchMethodError: java.util.LinkedList.push(Ljava/lang/Object;)V

    at org.yaml.snakeyaml.Yaml.load(Yaml.java:134)

由于Maven在中央回购协议中找不到snakeyaml,我手动将其安装到本地回购协议中。如果重要的话,我在Mac上使用snakeyaml 0.9和maven 2.0.9。

示例yaml文件

- 
    accountCode: foo
    accountId: 1
    email: foo@bar.com
    userId: 1

工作测试程序

import java.io.*;
import java.util.*;

import org.yaml.snakeyaml.Yaml;

/**
 * Testing SnakeYAML.

 * @author Hank Gay
 */
public final class Foo {
    public static void main(final String[] args) throws Exception {
        final Yaml yaml = new Yaml();
        Reader reader = null;
        try {
            reader = new FileReader("/tmp/foo.yaml");
            System.out.println(yaml.load(reader));
        } catch (final FileNotFoundException fnfe) {
            System.err.println("We had a problem reading the YAML from the file because we couldn't find the file." + fnfe);
        } finally {
            if (null != reader) {
                try {
                    reader.close();
                } catch (final IOException ioe) {
                    System.err.println("We got the following exception trying to clean up the reader: " + ioe);
                }
            }
        }
    }
}
