Creating a jar from a maven project in intellij
提问by Joe
I created a new maven project in IntelliJ and set packaging to jar but when I build it, the target folder does not contain a jar. I'm sure its something really dumb on my part but there are just so many different things i'm reading on different websites and I just feel better asking. 
我在 IntelliJ 中创建了一个新的 maven 项目并将打包设置为 jar 但是当我构建它时，目标文件夹不包含 jar。我确信这对我来说真的很愚蠢，但我在不同的网站上阅读了很多不同的东西，我只是觉得问得更好。

You need the maven jar plugin in order to create a jar
您需要 maven jar 插件才能创建 jar
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<mainClass>add your main class</mainClass>
</manifest>
</archive>
</configuration>
</plugin>

Assuming that the screen-shot shows the complete pom file, you are missing the entries that define the artifact. Try adding something like this following immediately after the tag:
假设屏幕截图显示了完整的 pom 文件，您将缺少定义工件的条目。尝试在标签后立即添加如下内容：
<modelVersion>4.0.0</modelVersion>
<groupId>com.mycompany.example</groupId>
<artifactId>stackoverflow-question</artifactId>
<version>0.0.1-SNAPSHOT</version>
You should end up with stackoverflow-question-0.0.1-SNAPSHOT.jar in your /target directory. You may need to refresh the directory to see it (You certainly have to in Eclipse)
您应该在 /target 目录中得到 stackoverflow-question-0.0.1-SNAPSHOT.jar。您可能需要刷新目录才能看到它（您当然必须在 Eclipse 中）

You should build you project using IDEA's Maven Projectsview.
您应该使用 IDEA 的Maven Projects视图构建您的项目。
View -> Tool Windows -> Maven Projects
查看 -> 工具窗口 -> Maven 项目
or open it from left bottom corner menu:
或从左下角菜单打开它：
And then build your project with maven goals - i.e. package:
然后使用 maven 目标构建您的项目 - 即包：
If packaging is set to jarin pom.xml, you will get a jar in targetdir.
如果 Packaging 设置为jarin pom.xml，您将在targetdir 中得到一个 jar 。

You need to have "jar" in packaging section of your pom.xml. You can add this before dependencies section:
您需要在 pom.xml 的包装部分中有“jar”。您可以在依赖项部分之前添加它：
<packaging>**jar**</packaging>
Then go to View -> Tool Windows -> Maven and in Maven window expand everything and double click on "package" in Lifecycle section.
然后转到 View -> Tool Windows -> Maven 并在 Maven 窗口中展开所有内容并双击 Lifecycle 部分中的“package”。
