[英]Export a jsprit maven project to an executable jar
I'm trying to create an executable .jar from a maven project using eclipse mars. 我正在尝试使用Eclipse Mars从Maven项目创建可执行文件.jar。 The project itself can be found on https://github.com/jsprit/jsprit 该项目本身可以在https://github.com/jsprit/jsprit上找到
So far I have successfully imported jsprit to eclipse as a maven project and I am able to run examples as Java Application. 到目前为止,我已经成功将jsprit作为maven项目导入到eclipse中,并且能够将示例作为Java应用程序运行。
I haven't yet been very successful at exporting it as an executable jar. 我还没有很成功地将其导出为可执行jar。 Let's say I want to export SimpleExample.java. 假设我要导出SimpleExample.java。 I have created the .jar but if I try to run jsprit-examples-1.6.2-SNAPSHOT-jar-with-dependencies.jar I get the following error message: 我创建了.jar,但是如果尝试运行jsprit-examples-1.6.2-SNAPSHOT-jar-with-dependencies.jar,则会收到以下错误消息:
Error: Could not find or load main class jsprit.examples.SimpleExample 错误:找不到或加载主类jsprit.examples.SimpleExample
The pom.xml which is located under jsprit-examples is following: 位于jsprit-examples下的pom.xml如下:

Everything else is as same as in the github repository. 其他所有内容都与github存储库中的相同。 I ran 'Maven Build...' on jsprit-examples. 我在jsprit-examples上运行了“ Maven Build ...”。 Under 'Edit Configuration->Goals' I did 'clean package assembly:single'. 在“编辑配置->目标”下,我执行了“清理程序包Assembly:single”。
This is my first experience with a maven build so it might be a very simple problem to someone who has some experience with maven. 这是我第一次使用Maven构建,因此对于具有Maven经验的人来说,这可能是一个非常简单的问题。
Thanks! 谢谢!
I you want to put all the dependencies in one executable jar, you need to create an uber-jar. 我想将所有依赖项放在一个可执行jar中,您需要创建一个uber-jar。 I usually do this with the maven shade plugin . 我通常使用Maven Shade插件执行此操作。
