java - NoClassDefFoundError:使用Gradle创建可运行的* .jar时出现org/slf4j/LoggerFactory

Question

我只是想借助gradle和应用程序插件为我的应用程序创建可运行的* .jar文件。

构建过程没有错误， list 文件可以正常运行，等等，但是在运行* .jar文件时会发生以下情况:

java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
    at main.Launcher.<clinit>(Launcher.java:19)
Caused by: java.lang.ClassNotFoundException: org.slf4j.LoggerFactory
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 1 more
Exception in thread "main" 
Process finished with exit code 1

似乎很明显我缺少该库，但是它已指定:

build.gradle

group 'Comparator'
version '0.9'

apply plugin: 'java'
apply plugin: 'application'

mainClassName = "main.Launcher"

compileJava {
    //enable compilation in a separate daemon process
    options.fork = true
    //enable incremental compilation
    options.incremental = true
}

repositories {
    mavenCentral()

}

}

jar {
    manifest {
        attributes 'Main-Class': mainClassName,
                'Class-Path': configurations.runtime.files.collect { "$it.name" }.join(' ')
    }
}

创建的 list 如下:

请注意，它确实包括slf4j，但我仍然遇到异常。
有任何想法吗？

谢谢!

一段时间后，我来到了(我认为是)解决方案。对生成的类路径有不同的依赖关系是一个大问题。从头开始生成项目并导入代码和资源被证明是成功的。

如果您遇到相同的错误，我提出相同的解决方案，则只需从头开始重建项目即可。

是的，可能有更好的解决方案，但我在1个月内找不到。
