buildscript {
    dependencies {
        classpath("com.bmuschko:gradle-tomcat-plugin:2.7.0")
    }
}

apply plugin: "com.bmuschko.tomcat"

dependencies {
    def tomcatVersion = '10.0.14'
    tomcat "org.apache.tomcat.embed:tomcat-embed-core:${tomcatVersion}",
            "org.apache.tomcat.embed:tomcat-embed-logging-juli:9.0.0.M6",
            "org.apache.tomcat.embed:tomcat-embed-jasper:${tomcatVersion}"

}

tomcat {
    httpProtocol = 'org.apache.coyote.http11.Http11Nio2Protocol'
    ajpProtocol  = 'org.apache.coyote.ajp.AjpNio2Protocol'
}

运行gradle tomcatRun命令会发现以下报错：
Caused by: java.lang.IllegalArgumentException: The AJP Connector is configured with secretRequired=“true” but the secret attribute is either null or “”. This combination is not valid

但gradle-tomcat-plugin插件并没有提供相关Ajp Connector的配置项。

最后在overflow找到了解决方法
https://*.com/questions/61340695/gradle-plugin-for-tomcat-9-0-34

将ajpProtocol = ‘org.apache.coyote.ajp.AjpNio2Protocol’
替换成
ajpProtocol = ‘org.apache.coyote.http11.Http11Nio2Protocol’
绕过Ajp的连接器协议
