java - Maven 和 graphql-java

Question

我正在尝试运行来自 http://graphql-java.readthedocs.io/en/stable/getting_started.html#hello-world 的 HelloWorld 示例

我有编译问题:

我的 Maven 文件:

我的 Maven 配置有什么问题？

Answer 1

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

<dependencies>
    <dependency>
        <groupId>com.graphql-java</groupId>
        <artifactId>graphql-java</artifactId>
        <version>2019-04-09T05-29-53-bd9240c</version>
    </dependency>
</dependencies>

如果你想使用最新的稳定版本(11.0.0)删除不必要的存储库声明并以这种方式使用它。

<!-- https://mvnrepository.com/artifact/com.graphql-java/graphql-java -->
<dependency>
    <groupId>com.graphql-java</groupId>
    <artifactId>graphql-java</artifactId>
    <version>11.0.0</version>
</dependency>
