使用的是IDEA,直接引入
1 2 3 | plugins { id 'com.github.johnrengelman.shadow' version '1.2.3' } |
放在build.gradle的最上面,然后执行shadowJar即可。
网上说有一种方法
1 2 3 4 5 6 7 8 9 | jar { manifest { attributes "Main-Class" : "$mainClassName" } from { configurations.compile. collect { it.isDirectory() ? it : zipTree(it) } } } |
这种方法确实打入进去了,但是运行的时候报错,异常如下:
1 2 3 4 5 6 7 | Exception in thread "main" java.lang.VerifyError: ( class : org/jboss/netty/channel/socket/nio/NioWorkerPool, method: newWorker signature: (Ljava/util/concurrent/Executor;)Lorg/jboss/netty/channel/socket/nio/AbstractNioWorker;) Wrong return type in function at org.elasticsearch.transport.netty.NettyTransport.createClientBootstrap(NettyTransport.java: 354 ) at org.elasticsearch.transport.netty.NettyTransport.doStart(NettyTransport.java: 290 ) at org.elasticsearch.common.component.AbstractLifecycleComponent.start(AbstractLifecycleComponent.java: 68 ) at org.elasticsearch.transport.TransportService.doStart(TransportService.java: 182 ) at org.elasticsearch.common.component.AbstractLifecycleComponent.start(AbstractLifecycleComponent.java: 68 ) at org.elasticsearch.client.transport.TransportClient$Builder.build(TransportClient.java: 162 ) |
不知道什么原因,不过用第三方插件暂时可以解决,原因慢慢排查了。
另外还有一种方法可以运行,不过依赖单独放入一个lib目录下,也就是jar和依赖分离的方法:
1 2 3 4 5 6 7 8 9 | jar { String someString = '' configurations.runtime. each {someString = someString + " lib//" +it.name} manifest { attributes 'Main-Class' : 'com.gridsum.techpub.legal.etl.App' attributes 'Class-Path' : someString } } |
以后用得到的时候再说~
