upgrade to SNAPSHOT version during developement

[yarix]

Here is my issue with SNAPSHOT using Git+Maven+RPM during development.

• i have 2 releases of myProject version 6.1.6 release 2_1 and 3_1.
  • upgrade from 2_1 to 3_1 is working fine with yum update.
  • these versions are from the release branch, where the POM have the correct release number e.g. <version>6.1.6-3</version>
  • the suffix _1 is added by the rpm plugin (as expected)

assuming i need to fix a bug in version 3_1:

• git checkout to feature branch
  • change the POM in the feature branch is <version>6.1.6-SNAPSHOT</version>
  • the RPMS are created as documented but, i can't upgrade to them since SNAPSHOT is "older" than "3_1"

What am i missing?
maybe the plugin use epoch for SNAPSHOT builds?

here is example of my yum repo:

yum list available myProject --show-duplicates

myProject.x86_64         6.1.6-SNAPSHOT20190430102710          feature-fixBug01-Artifactory
myProject.x86_64         6.1.6-SNAPSHOT20190430221146          feature-fixBug01-Artifactory
myProject.x86_64         6.1.6-2_1                             Artifactory
myProject.x86_64         6.1.6-3_1                             Artifactory

can you try to set version to 6.1.6-3.1-SNAPSHOT after releasing 6.1.6-3
this way you can upgrade.

thank you @dantran , i assume this trick will work.
i tried to stay simple, i preferred not touching the rpm version, letting the plugin do the job.
In them Maven pom.xml I define 6.1.6-SNAPSHOT and the CI (Jenkins) replace the SNAPSHOT with version 1,2,3... only on builds that are marked for release (the _1 is added by the plugin). for now, i don't want to touch this mechanism.

In the meantime, i will use the downgrade method in yum:
yum downgrade myProject-6.1.6-SNAPSHOT20190430221146
