Could not find javax.xml.xquery:xqj-api:1.0

Question

maven 存储库是否正确添加，并且是必需的？

如果是这样，添加xqj的语法是什么？

例外：

Answer 1

看这里 ： https://mvnrepository.com/artifact/javax.xml.xquery/xqj-api/1.0

该模块不托管在Maven central或JCenter存储库中，但可以在其他一些存储库中找到，例如：https://mvnrepository.com/repos/springio-plugins-release。

如果要向此模块添加依赖项，只需声明一个可用的托管存储库，例如：

在 Groovy DSL 中：

repositories {
    jcenter()
    mavenCentral()
    maven{            
        url "http://repo.spring.io/plugins-release/"
    }
}

Kotlin DSL

repositories {
    mavenCentral()
    jcenter()
    maven {
        setUrl("http://repo.spring.io/plugins-release/")
    }
}
