逗人，
我对Grandle来说是全新的，所以请耐心等待。
我有一个在IDE中运行良好的应用程序。它基于Google Sheet API的教程，并附带了一些其他功能。
运行第一次构建后，.jar文件告诉我它没有定义Main函数，但是添加了
jar {
manifest {
attributes 'Main-Class': 'WordCards'
}
}
解决了这个问题。现在当我尝试在IDE之外运行.jar时，我会遇到很多例外情况，包括由InvocationTargetException
ClassNotFoundException
我想包装上的东西不对，但我不知道要找什么。
这是gradle文件：
apply plugin: 'java'
apply plugin: 'application'
mainClassName = 'WordCards'
sourceCompatibility = 1.8
targetCompatibility = 1.8
version = '1.0'
repositories {
mavenCentral()
}
jar {
manifest {
attributes 'Main-Class': 'WordCards'
}
}
dependencies {
compile 'com.google.api-client:google-api-client:1.22.0'
compile 'com.google.oauth-client:google-oauth-client-jetty:1.22.0'
compile 'com.google.apis:google-api-services-sheets:v4-rev10-1.22.0'
}
这就是其中一个类的样子（这不是主类，我正在复制这个类，因为我怀疑这个类有导致错误的依赖项）：

再一次，代码在IDE中运行良好
