我通过 gvm 安装了 grails 3.0.1 并尝试通过调用创建一个新的 grails 项目
# grails create-app myproject
| Error Error occurred running Grails CLI: org.yaml.snakeyaml.Yaml.loadAs(Ljava/io/InputStream;Ljava/lang/Class;)Ljava/lang/Object; (Use --stacktrace to see the full trace)
完整的错误信息如下：
# grails --verbose --stacktrace create-app myproject
| Error Error occurred running Grails CLI: org.yaml.snakeyaml.Yaml.loadAs(Ljava/io/InputStream;Ljava/lang/Class;)Ljava/lang/Object;
java.lang.NoSuchMethodError: org.yaml.snakeyaml.Yaml.loadAs(Ljava/io/InputStream;Ljava/lang/Class;)Ljava/lang/Object;

（grails 3.0.0 也会出现同样的错误。使用 java 1.8.0_45 而不是 1.8.0_31 时，错误仍然存在。）
有任何想法吗？

编辑：
我调用grails create-app myproject了一台 Windows 机器并将文件夹复制到我的 Mac 上。然后我跑
# grails compile --debug --stacktrace
FAILURE: Build failed with an exception.
* What went wrong:
Could not create an instance of type org.gradle.api.internal.project.DefaultProject_Decorated.
> com.google.common.base.Splitter.splitToList(Ljava/lang/CharSequence;)Ljava/util/List;
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
BUILD FAILED
