Tomcat installation issue - "Could not find or load main class"

Question

I want to create a 'Dynamic web project' in eclipse. To do so, I want Tomcat to be listed in 'Target runtime' combo. So, I'm trying to install Tomcat. I changed the mode of all .sh files in TOMCAT_HOME/bin as follows;

1. [root@localhost opt]# cd apache-tomcat-7.0.12/bin/
2. [root@localhost bin]# chmod 0755 *.sh

I could see that there is a problem with my installation. How to resolve the below errors and install tomcat successfully?

On executing ./version.sh command, I get the following

Using CATALINA_BASE:   /home/admin/apache-tomcat-9.0.0.M6-src
Using CATALINA_HOME:   /home/admin/apache-tomcat-9.0.0.M6-src

On executing ./configtest.sh, I get the following error;

Look at this evidence you gave us on the question:

Using CATALINA_BASE:   /home/admin/apache-tomcat-9.0.0.M6-src

The "-src" means that you have downloaded the source code which requires to be built.

Download the "bin distribution", for example the first file on the "Core" section in this link https://tomcat.apache.org/download-80.cgi

Now it will run. Anyway, refer to the RUNNING.txt file on the main installation folder and you will be fine.
