   Fixed in devel (29e3392):

   • msiUpgradeCode now defaults to a stable GUID derived from organizationName and name (the build logs it), so a new MSI upgrades the installed version.
   • productVersion and fileVersion default to version as x.x.x.x (e.g. 2.1.0-SNAPSHOT becomes 2.1.0.0), or 1.0.0.0 with a warning if it doesn't fit an MSI version.
   • Installing the same version again replaces it (AllowSameVersionUpgrades).

   The Windows smoke tests build the MSI with WiX 5; the upgrade itself isn't tested in CI, so feedback is welcome.

   It will ship in 2.0.1, and I'll close this issue then.

   How to test 2.0.1-SNAPSHOT

   Important

   Since 2.0.0 the groupId, the Gradle plugin id and the Java packages are io.github.javapackager (see Upgrading to 2.0).

   Maven, add the snapshots repository and use the snapshot version:

   <pluginRepositories>
       <pluginRepository>
           <id>central-portal-snapshots</id>
           <url>https://central.sonatype.com/repository/maven-snapshots/</url>
           <releases><enabled>false</enabled></releases>
           <snapshots><enabled>true</enabled></snapshots>
       </pluginRepository>
   </pluginRepositories>
   [...]
   <plugin>
       <groupId>io.github.javapackager</groupId>
       <artifactId>javapackager</artifactId>
       <version>2.0.1-SNAPSHOT</version>
       [...]
   </plugin>

   Gradle, add the snapshots repository in settings.gradle:

   pluginManagement {
       repositories {
           maven { url = 'https://central.sonatype.com/repository/maven-snapshots/' }
           gradlePluginPortal()
       }
   }

   and use the snapshot version in build.gradle:

   plugins {
       id 'io.github.javapackager' version '2.0.1-SNAPSHOT'
   }

   See Snapshot versions for more.
