If you don't use boot repackage you can simply disable bootRepackagetasks by adding this line into your build.gradle file:

如果您不使用引导重新打包，您可以bootRepackage通过将此行添加到您的 build.gradle 文件中来简单地禁用任务：

bootRepackage.enabled = false

Otherwise you need to specify the main class:

否则，您需要指定主类：

bootRepackage {
    mainClass = 'youPackage.Application'
}

You can find more instructions in this link

您可以在此链接中找到更多说明

Share your build.gradle if you still have problem.

如果仍有问题，请分享您的 build.gradle。

From Spring Boot release 2.0 M1the bootRepackagetask has been replaced with bootJarand bootWartasks.

从Spring Boot 2.0 M1 版开始，该bootRepackage任务已被替换为bootJar和bootWar任务。
