gradle 打包 jar （一波三折）
第一次尝试，打包成功，运行失败
build.gradle 打包
jar {
baseName 'testJar'
from {
//添加依懒到打包文件
//configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
configurations.runtime.collect{zipTree(it)}
}
manifest {
attributes 'Main-Class':"com.example.elasticbeatsfilebeat.ElasticBeatsFilebeatApplication"
}
}
运行结果
F:\IdeaProjects\elastic-beats-filebeat\build\libs>java -jar testJar-0.0.1-SNAPSHOT.jar
错误: 找不到或无法加载主类 com.example.elasticbeatsfilebeat.ElasticBeatsFilebeatApplication
原因分析
gradle打包的jar有一种签名的机制，无法直接java -jar执行
[root@CentOS7 filebeats]# java -jar elastic-beats-filebeat-0.0.1-SNAPSHOT.jar
Error: A JNI error has occurred, please check your installation and try again

第二次尝试，处理签名认证问题
用exclude排除签名认证相关的文件
jar {
baseName 'testJar_before_dependencies'
from {
//添加依懒到打包文件
configurations.runtime.collect{zipTree(it)}
}
manifest {
attributes 'Main-Class':"com.example.elasticbeatsfilebeat.ElasticBeatsFilebeatApplication"
}
exclude('LICENSE.txt', 'NOTICE.txt', 'rootdoc.txt')
exclude 'META-INF/*.RSA', 'META-INF/*.SF', 'META-INF/*.DSA'
exclude 'META-INF/NOTICE', 'META-INF/NOTICE.txt'
exclude 'META-INF/LICENSE', 'META-INF/LICENSE.txt'
exclude 'META-INF/DEPENDENCIES'
}
又TM报错了

原因分析
缺失配置，但是还是不懂什么意思，直接看怎么解决吧
解决方案
找到jar文件中 META-INF/spring.factories
在最后加上
