g667 opened a new issue, #11196:
URL: https://github.com/apache/maven/issues/11196
### Affected version
4.0.0-rc-4
### Bug description
# Changes to ${revision} in profiles do not propagate to the final project
version
## Expected behavior
When the POM references <version>${revision}</version>, the resolved value
of ${revision} should determine the project version.
## Observed behavior
${revision} is resolved correctly, but its value is not applied to the final
project version.
## Steps to reproduce
Execute the provided pom.xml file
### Case 1: No profile activated
Expected final version includes "+dev"
```
mvn clean
...
[INFO] Building m4-demo-revision 0.2.0+dev
...
baseVersion : 0.2.0
revision : 0.2.0+dev
project.version: 0.2.0+dev
version : 0.2.0+dev
```
### Case 2: Release profile activated
Expected final version is only baseVersion without "+dev"
```
mvn clean -PreleaseBuild
...
[INFO] Building m4-demo-revision 0.2.0+dev
...
baseVersion : 0.2.0
revision : 0.2.0
project.version: 0.2.0+dev
version : 0.2.0+dev
```
### Case 3: Manipulation profile activated (setting ${version} directly)
${version} is set directly and the change is applied, but it still does not
affect the final project version
```
mvn clean -PmanipulateVersion
...
[INFO] Building m4-demo-revision 0.2.0+dev
...
baseVersion : 0.2.0
revision : 0.2.0+dev
project.version: 0.2.0+dev
version : 0.2.0
```
Note: This is not the intended use case, but it illustrates the difference
between the variable resolution phase and the phase where the project version
is applied, showing that runtime changes to variables may not propagate to the
final version.
## Environment
Maven : 4.0.0-rc-4 (bed0f8174bf728978f86fac533aa38a9511f3872)
