Unknown version of Tomcat was specified in Eclipse

Question

I want to add latest tomcat-7 0 42 in my eclipse  Probably eclipse tomcat server adapter 7 only supports tomcat version upto 7 0 12        So please help me how can I configure my eclipse with tomcat-7 0 42

To recognise your Tomcat installation folder, Eclipse is scanning for the following files:

conf/catalina.policy
conf/server.xml
conf/web.xml
conf/context.xml
conf/tomcat-users.xml
conf/catalina.policy
conf/catalina.properties
lib/catalina.jar

so make sure you're pointing to the right place and have the right read permissions.

E.g.

OS X (if installed via brew), it's: /usr/local/opt/tomcat/libexec
Linux/Ubuntu: see: Tomcat and Eclipse Integration Error

This happened to me because Tomcat was still in the process of downloading  Download and Install   The message disappeared after a few minutes   The eclipse window should really have some type of progress indicator showing download status

I know this is and oldie but i had this issue recently with the latest versions of Tomcat and Eclipse on Windows 10   It was a permissions issue  All i had to do was navigate to the Tomcat install directory and open the folder  I was prompted to access the folder as an Administrator   After this the versions were recognised by Eclipse and I could add the new runtime

Probably  you are trying to point the tomcat directory having the source folder  Please download the tomcat binary version from here  For Linux environments  there you can find  zip and  tar gz files under core section  Please download and extract them  after that  if you point this extracted directory  eclipse will be able to identify the tomcat version  Eclipse was not able to find the version of tomcat  since the directory you pointed out didn t contain the conf folder  Hope this helps

As soon as you provide the directory where Tomcat needs to be installed and click ok you can notice download and installation starts in the progress tab of Eclipse     Let the process complete The error will automatically disappear     Note  It is not mandatory to name your folder CATALINA HOME  I have tested this with windows  Cannot assert the same for Linux but IMO same rule should apply

You are pointing to the source directory  You can run a build by running ant from that same directory  then add   output build  to the end of the installation directory path

User · Answer

You are specifying tomcat source directory   You need to specify tomcat binary installation root directory  also known as CATALINA HOME   Usually  this is where you untar apache-tomcat-7 0 42 tar gz file

I got the same error and resolved it by giving enough permissions to the folder  I gave full permissions by  you can try limited permissions which is enough for eclipse to run tomcat   sudo chmod -R 777 apache-tomcat-8 5 33    FYI  I encountered this error on my mac  but I think it should be same for ubuntu system too

User · Answer

It may be due to the access of the tomcat installation path C  Program Files Apache Software Foundation Tomcat 9 0  wasn t available with the current user
