是否可以使用eclipse和share来构建一个java项目？ [英] Is it possible to build a java project only once using eclipse and share?

问题描述

是否可以实际构建一个包含要编译的java代码的maven项目，并且二进制文件可以共享？

is it possible to actually build a maven project containing java code to be built once and the binaries can be shared?

问题：我正在尝试构建项目将需要大约3-4个小时，需要较高的互联网带宽。我试图检查在其他几台机器之间重新使用这个内置项目的可能性。

Problem: The project i am trying to build would take me about 3-4 hours and requires high internet bandwidth. I am trying to check the possibility of re using this built project among several other machines.

我早期使用了涉及makefile的c ++项目，这很简单。我是Java / eclipse的新手，需要帮助才能确定这是否真的有可能。

I have worked with c++ projects involving makefiles earlier and this was pretty simpler. I am new to Java / eclipse and would need help to figure out if this is something really possible.

PS：
我试图找到现有的解决方案;他们不是星空前进，或者他们说这不能完成

PS: I did try to find existing solutions; they were not staright forward or they say that this cant be done

推荐答案

构建一次并脱机分享

在Maven中，您只能将仅构建一次，并获取完全包装所有依赖关系的JAR文件。所以你可以将这个JAR分享给其他机器。

Build once and share it offline

In Maven, you can build your project only once and get a JAR file fully packed with all dependencies. So that, you can share this JAR to other machines off-line.

以下是执行步骤。

1. 首先使用以下设置更新您的pom.xml

 <build>
  <plugins>
    <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>
        <archive>
          <manifest>
            <mainClass>com.thanga.MyTest[REPLACE WITH YOUR MAIN CLASS]</mainClass>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
    </plugin>
  </plugins>
</build>

1. 打包你的项目，目标是 package assembly：single 如下所示

1. Package your project with the goal package assembly:single as shown below

在控制台中，

 mvn package assembly:single

在eclipse中，

1. 运行这个，你可以得到两个JAR文件。其中一个 MyFullPack-0.0.1-SNAPSHOT-jar-with-dependencies.jar 具有加载完整的
   依赖项。

1. Run this and you can get the two JAR files. One of them MyFullPack-0.0.1-SNAPSHOT-jar-with-dependencies.jar has the full dependencies loaded.

1. 您可以打开JAR查看依赖关系如下所示打包。

1. 您可以离线共享此JAR到其他机器，无需任何更多的构建>
   

1. You can share this JAR to other machines off-line without any more build
