java下载javax。使用maven的json

Question

我正在尝试使用javax。json库，所以我将其添加到pom中。xml文件，如下所示：

<dependency>
    <groupId>javax.json</groupId>
    <artifactId>javax.json-api</artifactId>
    <version>1.0</version>
</dependency>

这个在标签里面。但是，当我尝试运行我的项目doing run as，然后将目标设置为“package”或“install”时，我希望在我的Maven依赖项库中看到json库，就像Junit等其他库一样。但我什么也没看到。因此，如果您对问题可能来自何处有想法，请让我知道

附言：我是新手

在Eclipse中，您必须右键单击该项目并选择“Maven….Update project”以及pom中新添加的库。xml文件将下载到您的库目录
