Josh Juneau commented on NETBEANS-5143:
---------------------------------------
I have attempted to replicate this issue on Mac OS X and was unable to do so.
I suspect this may be a Windows-only issue? Perhaps someone else on OS X can
confirm.
I did the following:
1) Create new Maven web application
2) Set Tomcat server in "Run"
3) Build and Run project.
I only see the one deployment.
Subsequently, I attempted to run the same application on GlassFish and had no
issues.
My configuration is as follows:
OS: OS X 11.2.3
JDK: Java 1.8.0_171
NetBeans 12.4
Tomcat: 9.0.46.0
GlassFish 6
> NetBeans 12.2, 12.3, 12.4 deploys webapps twice

> Key: NETBEANS-5143
> URL: https://issues.apache.org/jira/browse/NETBEANS-5143
> Project: NetBeans
> Issue Type: Bug
> Components: core
> Affects Versions: 12.2, 12.3, 12.4
> Environment: Windows 10 20H2/AMD Ryzen 7 4800H/32GB RAM
> java: build 11.0.9.1+1, maven 3.6.3
> Netbeans versions tested: 12.1, 12.2, 12.3, 12.4 (12.2/12.3/1.4 are effected)
> Tomcat (new installs): 8.5.60, 9.0.40, Payara (per Patrick Musembi)
> Reporter: Vlad Palnik
> Priority: Major
> Labels: webapp, webapp-deployment
>
> 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
>
> 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. Build/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/build make sure same server and java versions are selected
> 7 Build/Run project
> 8 Check build log, you will see two deploys of webapp
>
>
> BUILD SUCCESS
