我试图从this project构建单个jar以在其他计算机上运行。
我尝试从命令行构建它：
clustertag/out/production/ClusterTag$ jar cmvf META-INF/MANIFEST.MF app.jar no/simula/clustertag/*.class

但是当我尝试运行它时，我收到错误：
java -jar app.jar

此外，我尝试在Intellij Idea中将其构建为工件，但也会出错：

在libbin文件夹项目中有一些.so dependensies，那么可能会导致问题？
答案 0 :(得分：0)
最后我从命令行解决了它：
jar cmvf META-INF/MANIFEST.MF app.jar no/simula/clustertag/*.class
在META-INF/MANIFEST.MF中我添加了libs：
Manifest-Version: 1.0
Main-Class: no.simula.clustertag.Main
Class-Path: lib/ibxm.jar lib/jinput.jar lib/jnlp.jar lib/jogg-0.0.7.jar lib/jorbis-0.0.15.jar lib/lire.jar lib/lwjgl.jar lib/lwjgl_util.jar lib/lwjgl_util_applet.jar lib/natives-linux.jar lib/slick.jar lib/tinylinepp.jar
并通过java -Djava.library.path=libbin -jar app.jar
