appengineRun starts two instances of spring boot 2.0.2 servlet #269

Closed sullrich84 closed 2 years ago

sullrich84 commented 6 years ago

Hi,

when I use appengineRun to start a local instance of my project, two instances of the same servlet will be startet. I came accross the following log message: 2 Spring WebApplicationInitializers detected on classpath. The compiled war file runs perfectly on jetty standalone (with just one instance booting). Any ideas how I can fix this?

Logs form appengineRun:

15:46:39: Executing task 'appengineRun'...

@sullrich84 I'm still trying to find someone who might know the answer, did you figure it out?
