Scala和sbt新手在这里。我创建了一个使用casbah的Scala sbt项目
libraryDependencies += "org.mongodb" %% "casbah" % "3.1.1"
查询mongodb并以地图形式返回结果。我想在Java Maven项目中使用此代码来处理从查询数据库中获得的结果。
我将其添加到build.sbt文件中：
publishMavenStyle := true
publishTo := Some(Resolver.file("file", new File(Path.userHome.absolutePath + "/.m2/repository")))
在我的.m2本地存储库中安装jar文件。这是我执行
sbt publish时的输出：> publish

然后，我将此依赖项导入了pom文件：
<dependency>
<groupId>edu.cmu.cs.mvelezce</groupId>
<artifactId>mongo_2.12</artifactId>
<version>0.1.0-SNAPSHOT</version>
</dependency>
运行
mvn compile时，出现以下错误：[ERROR] Failed to execute goal on project performance-mapper: Could not resolve dependencies for project edu.cmu.cs.mvelezce:performance-mapper:jar:0.1.0-SNAPSHOT: Failure to find org.mongodb:casbah_2.12:jar:3.1.1 in https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1]
我知道casbah有几个模块，我只能导入几个模块，而不是全部模块。但是，按照Casbah中的文档，我添加了enterie库。我还看着Maven Central，这个版本的casbah没有罐子。仅独立模块。我在pom中添加了其中一些模块，但是仍然遇到与上面相同的错误。 Maven正在寻找完整的jar文件。
有没有办法来解决这个问题？我以为我只能在build.sbt文件中添加所需的Scala依赖项，但是这样做时出现编译错误。有人建议吗？
谢谢！
最佳答案
您需要确保在项目中，Casbah依赖项的类型为pom。例如，在您的pom.xml中添加以下内容：
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>casbah_2.11</artifactId>
<version>3.1.1</version>
<type>pom</type>
</dependency>
