How to invoke a JAR resides in the maven local repository?
问题
作为CI/CD流程的一部分，我正在从Maven仓库（Sonatype Nexus）中获取一个JAR文件。
现在，我想要简单地运行“java -jar”命令。
最简单的方法是什么？
我只需要使用命令java -jar ${MAVEN_HOME}/repository/com/company/path/to/my/x.jar吗？
还是有更简单的方法？

As part of a CI/CD process, I'm pulling a JAR from a maven repository (Sonatype nexus)
Now, I'd like to simply "java -jar" it.
What is the simplest way to do it?
Should I just use the command java -jar ${MAVEN_HOME}/repository/com/company/path/to/my/x.jar?
Or is there a simpler way?

你可以创建一个sh文件，并将以下内容添加到文件中以下载jar包：
wget --user USERNAME --password PASSWORD 上传jar包的Nexus URL
java -Djava.security.egd=file:/dev/./urandom -jar jar包的名称.jar
exec "$@"
> 下一步将帮助你将jar包下载到另一个项目中
在你的pom.xml中，你需要添加repository标签：
<repositories>
<repository>
<id>remote</id>
<url>托管jar包的URL</url>
</repository>
</repositories>
如果你的远程仓库受密码保护，你还需要添加setting.xml文件：
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
http://maven.apache.org/xsd/settings-1.0.0.xsd">
<servers>
<server>
<id>remote</id>
<username>***</username> <!-- 用户名 -->
<password>****</password> <!-- 密码 -->
</server>
</servers>
</settings>
之后，在你的pom.xml中添加依赖项，它将会下载jar包到本地的m2文件夹：
<dependency>
<groupId>项目的groupId</groupId>
<artifactId>项目的artifactId</artifactId> <!-- jar包的artifactId -->
<version>项目的版本号</version>
</dependency>
在创建jar包时，你需要添加这些groupId、artifactId和version信息。
英文:
You can create a sh file and this to download jar
wget --user USERNAME --password PASSWORD url of the nexus where the jar is uploaded
java -Djava.security.egd=file:/dev/./urandom -jar name of the jar.jar
exec "$@"
> The Next step will help you to download jar to another project
In your pom.xml you need to add repository tag
<repositories>
<repository>
<id>remote</id>
<url>Url where you have hosted the jar</url>
</repository>
</repositories>
Also, you need to add setting.xml if your remote is password protected
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
http://maven.apache.org/xsd/settings-1.0.0.xsd">
<servers>
<server>
<id>remote</id>
<username>***</username> //username
<password>****</password> //password
</server>
</servers>
</settings>
After that add dependency in your pom.xml, it will download the jar to you local m2 folder
<dependency>
<groupId>group id of project</groupId>
<artifactId>artifact of project</artifactId> //artifact of your jar
<version>version of your project</version>
</dependency>
This groupId, artifactId and version that you need to add when you will create the jar
