构建失败 - gradle

Question

我正在使用 Gradle 构建我的应用程序。我无法构建，因为它显示“启动 Tomcat 服务器时发生错误”我实际上是在尝试构建 spring 教程http://spring.io/guides/tutorials/web/ 提供的应用程序@

我检查了没有其他进程在端口 8080 上运行

有人可以建议我做错了什么

这是错误的完整堆栈跟踪

BUILD FAILED

Answer 1

问题出在 build.gradle 文件上

maketomcatRunWar.contextPath = ''

到

tomcatRunWar{
    contextPath = ''
    httpPort = 8080
    stopPort = 8191 
}

Answer 2

您的问题肯定与停止端口有关。由于您没有设置它，因此tomcat使用的是默认值（8081）。尝试改变它：

tomcatRunWar.stopPort = 8181
