我的配置： - Gradle 版本：4.9 - JDK 版本：jdk1.8.0_111 - Windows 10

由于您在 Windows 上使用 Gradle，因此如果类路径中有大量依赖项，您可能会遇到此错误。这是由于执行命令的字符数限制造成的。

从另一个线程尝试这个解决方案：

plugins {
    id "com.github.ManifestClasspath" version "0.1.0-RELEASE"       
}

apply plugin: "com.github.ManifestClasspath"

springBoot {
    mainClassName = 'com.pb.ngp.identity.manager.KeyManagerApplication'
}

您可能会遇到以下错误：

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':bootRun'.

Caused by: org.gradle.api.InvalidUserDataException: Main class name has not been configured and it could not be resolved

然后简单指定主类。例如

springBoot {
    mainClassName = 'com.example.SpringBootApplication'
}
