"A problem was found with the configuration of task ':shadowJar' (type 'ShadowJar')." 无法创建 discord bot jar

Question

我正在尝试制作一个 discord 机器人并使用 shadow jar 导出 jar。

 my build.gradle file:

 plugins {
    id 'java'
    id 'application'
    id 'com.github.johnrengelman.shadow' version '2.0.4'
}

mainClassName = "Main"

group 'de.max'
version '1.0'

sourceCompatibility = 1.8
repositories {
    mavenCentral()
    jcenter()
}

dependencies {
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.6.0'
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine'
    compile 'net.dv8tion:JDA:4.2.0_247'
}
test {
    useJUnitPlatform()
}

当我尝试执行它时出现此错误：（它说我没有设置属性 mainClassName，但我设置了）

FAILURE: Build failed with an exception.

What went wrong: A problem was found with the configuration of task ':shadowJar' (type 'ShadowJar').

No value has been specified for property 'mainClassName'.

尝试：运行使用 --info 或 --debug 选项以获得更多日志输出。运行使用 --scan 以获得完整的见解。

您应该更新影子插件。最新版本可以在 github.

上找到

id 'com.github.johnrengelman.shadow' version '6.0.1'

我强烈建议关注 JDA Setup Guide。
