我有一个使用Maven构建的独立Java程序.所有依赖项都在Maven中指定.当我想在不同的环境中运行这个独立的Java程序时，我将必须复制所有相关的jar文件并将其设置在类路径中.这是我必须采取的方法还是有更好的方法可用?

I have a standalone java program which is built using Maven. All the dependencies are specified in Maven. When I want to run this standalone java program in a different environment , I will have to copy all the relevant jar files and set it in the classpath. Is this the approach that I must take or is there a better approach available?

推荐答案

以下内容可能会为您提供帮助:用Maven打包Java源代码时，只需将调用添加到依赖项"插件的复制依赖项"目标中，通过这种方式:

Following could maybe help you: when packaging your Java source with Maven, just add the call to the "copy-dependencies" goal of the "dependency" plugin, in this way:

mvn clean package dependency:copy-dependencies

如Dependency插件文档中 http://maven.apache.org所述/plugins/maven-dependency-plugin/，它将获取项目直接依赖项列表以及可选的传递性依赖项列表，并将它们复制到指定位置，并在需要时剥离版本.

As explained in the Dependency plugin doc at http://maven.apache.org/plugins/maven-dependency-plugin/, this will takes the list of project direct dependencies and optionally transitive dependencies and copies them to a specified location, stripping the version if desired.

默认情况下，所有传递性依赖项都将被复制到目标/依赖项"中，从而使类路径的定义变得非常容易.

By default, all the transitive dependencies will be copied into "target/dependency", making the definition of your classpath very easy.

通过将本地存储库中的依赖项的类路径字符串输出到文件或日志中，同一依赖项"插件的另一个目标"build-classpath"也可以为您提供帮助(请参见

Another goal called "build-classpath" of the same "dependency" plugin could also help you, by outputting a classpath string of dependencies from the local repository to a file or log (see http://maven.apache.org/plugins/maven-dependency-plugin/build-classpath-mojo.html)
