【问题描述】：

我是 Maven 和 Gradle 的完整初学者。我有一个工作的 Maven 项目。现在我想从另一个使用 Gradle 构建的项目中添加一堆类。我想从 Gradle 项目中获取课程并在我的 Maven 项目中使用它。当我将这些类复制到我的 Maven 项目中时，我得到了一堆依赖错误。为了解决这些错误，我想将所需的内容添加到我的 pom.xml 文件中。

基本上，我想将build.gradle 文件中指定的所有依赖项添加到我的pom.xml 文件中。

pom.xml 文件：

【问题讨论】：

您是否需要同时构建所有内容（maven 调用 gradle）或者您可以构建 gradle 库并将其安装到 maven，然后使用这些库构建基于 maven 的项目？
@the_storyteller 后者。我不需要 Gradle 项目，我只想用 Maven 构建和安装 Gradle 库。

标签： java maven gradle build.gradle pom.xml

【解决方案1】：

要部署到 Maven，请使用 maven 插件。

apply plugin: 'maven'

group = 'com.company'
version = '1.0.0.6'
// To build and push development snapshots, add a suffix to the name
// version = '1.0.0.6-SNAPSHOT'

artifacts {
    archives jar
}

uploadArchives {
    repositories {
        mavenDeployer {
            snapshotRepository(url: 'https://maven.repo/bla') {
                authentication(userName: snapshotUser, password: snapshotPassword)
            }
            repository(url: 'https://maven.repo/bla') {
                authentication(userName: releaseUser, password: releasePassword);
            }
        }
    }
}

您既可以通过运行uploadArchives 任务安装到远程存储库（上面的示例是https://maven.repo/bla），也可以使用install 安装到maven 本地的~/.m2/repository任务。

gradle install uploadArchives

如果您选择安装到本地 maven，您可以使用 dependencies { mavenLocal() } 或将其包含在您的 pom.xml 中，将对本地 maven 的依赖添加到其他 gradle 项目中

<settings <!-- bla --> >
  <localRepository>${user.home}/.m2/repository</localRepository>
</settings>

【讨论】：

我无法按照您的回答：/ 我知道您建议修改 .gradle 文件，然后运行应该生成等效 pom.xml 文件的 Gradle 命令？您能否指出我在具体示例中需要采取的步骤？
对不起。将上面的 gradle 代码添加到你的 gradle 文件中，然后运行 gradle build install，这将构建 gradle 项目并将其安装到 mavenLocal。之后，将 localRepository 代码添加到您的 pom.xml <settings/> 块中，理论上您将能够使用 mavenLocal 存储库中的 gradle-build 工件。如果要安装到远程存储库，则需要更改远程存储库的 url 和凭据，然后运行 gradle uploadArchives。
