Tomcat installation at this directory is version 9.0.0.M26. A Tomcat 8.0 installation is expect

tomcate:apache-tomcat-9.0.0.M26

eclipse:Version: Luna Service Release 2 (4.4.2)

背景：

在eclipse中添加 server -> Runtime Environment -> Add -> Apache Tomcate v8.0 -> Next -> Tomcate installation diretory -> Browse -> apache-tomcat-9.0.0.M26

-> The Apache Tomcat installation at this directory is version 9.0.0.M26.  A Tomcat 8.0 installation is expected.

解决方法：进入 tomcate的安装目录里，E:\Develop software\apache-tomcat-9.0.0.M26\lib，解压 catalina.jar ， 进入 \org\apache\catalina\util\，编辑 ServerInfo.properties

server.info=Apache Tomcat/9.0.0.M26
server.number=9.0.0.0
server.built=Aug 2 2017 20:29:05 UTC

改为

server.info=Apache Tomcat/8.0.0
server.number=8.0.0
#server.info=Apache Tomcat/9.0.0.M26
#server.number=9.0.0.0
server.built=Aug 2 2017 20:29:05 UTC

即可。

注意：如果直接改不生效，可以在cmd窗口中解压 catalina.jar ，修改ServerInfo.properties，压缩成新的catalina.jar，替换原来的catalina.jar即可。

附上命令：

解压：jar xvf catalina.jar

压缩：jar cvf catalina.jar ./*
