Maven和graphql的Java

HelloWorld示例我有编译问题：

我Maven的文件：

<?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"

      <artifactId>graphql-java</artifactId> 
      <version>3.0.0</version> 
     </dependency> 
    </dependencies> 
</project> 

有什么不对我的Maven组态？

要使用bintray存储库中的最新版本，请更改依赖版本。你可以找到版本here。

<dependencies> 
    <dependency> 
     <groupId>com.graphql-java</groupId> 
     <artifactId>graphql-java</artifactId> 
     <version>2017-07-25T02-45-22</version> 
    </dependency> 
</dependencies> 

如果你想使用最新的稳定版本（3.0.0）去掉不必要的仓库声明和使用这种方式。

<!-- https://mvnrepository.com/artifact/com.graphql-java/graphql-java --> 
<dependency> 
    <groupId>com.graphql-java</groupId> 
    <artifactId>graphql-java</artifactId> 
    <version>3.0.0</version> 
</dependency>
