Description
To whomever it concerns,
Bug in NetBeans 12.2/12.3/12.4. Netbeans seems to interfere with the deployment of web apps somehow and web apps are deployed twice.
While deploying an app it follows this pattern: deploy => undeploy => deploy (see build log below). I tried solving this issue by undeployed any previous versions of the app manually and restarted Tomcat, the same error occurs. The issue appears when using NB 12.2/12.3/12.4.
When tested on NetBeans 12.1 using the same Java/Tomcat installation/config no errors occur and deployment proceeds correctly.
Steps to replicate:
1: Create maven webapp (Java EE7, Java 11) in NetBeans 12.1
2 Set Tomcat Server in Properties > Run
3 Clean -> Run project in 12.1, you will get a "Hello World" basic site.
4. Check build log, only a single deploy should show up.
5 Close 12.1 and open same project in 12.2/12.3/12.4
6 Before run make sure same server and java versions are selected
7 Clean -> Run project
8 Check build log, you will see two deploys of webapp
BUILD SUCCESS
