Having a batch file check its own output?

batch-file, command-line, maven

Solution

I like vane's idea to take action upon the return code provided by mvn, but instead of using ERRORLEVEL, I like to use the `||` operator. The commands after `||` are only excecuted if the prior command failed.

::initialize error flag to undefined
set "mvnErr="

::run your Maven command and define the error flag if there was an error
call mvn {your arguments here} || set mvnErr=1

::You can now take action if there was an error
if defined mvnErr echo there was a Maven error

Problem

I'm wondering if it's possible to have a batch file check itself for a string. I'm using a batch file to run Maven commands,and I want to check if anything failed by searching for a "FAILURE" string at the end of the script I know you can `FIND` in other files, but can you have it check the current output on itself, or is the best solution to save the batch file output as a text and then search it? As an example, if I had a batch file `echo Hello World` it would print `Hello World`, then I would want to search the output for `Hello` and tell me it found the string `Hello`.
