----------------------------------------
Summary: Maven reactor doesn't work well for a multimodule project
when enabling build cache
Key: MBUILDCACHE-78
URL: https://issues.apache.org/jira/browse/MBUILDCACHE-78
Project: Maven Build Cache Extension
Issue Type: Bug
Affects Versions: 1.1.0
Environment: macOS Sonama, Java 17, Maven 3.9.6
Reporter: Hongxin Liang
In a multimodule project, as a simplest example:
[https://github.com/honnix/cache|https://github.com/honnix/cache),],"mvn
compile" with build cache enabled doesn't play well with Maven reactor. A few
scenarios I have tested in the provided repro example:
# With a clean environment (no build cache, no "mvn install" have been done)
## Run "mvn compile" and everything works
## Modify (putting a random empty line will suffice) class "B" in module "b"
## Run "mvn compile" again, and now it fails when trying to download snapshot
of module "a" from maven central (after failing to find that in my local repo)
# With a clean environment (no build cache)
## Run "mvn install" and everything works
## Modify class "A" in module "a" to rename the method
## Run "mvn compile" for the first time, and it fails to compile due to
renaming of the method in class "A"
## Run "mvn compile" for the second time, nothing fails but apparent the code
is still wrong; run more "mvn compile" and still nothing fails
## Running "mvn install" fails the build due to compilation error
I'm not entirely sure I am doing things properly and I'm not sure whether the
config is correct either (I took the example as
[https://maven.apache.org/extensions/maven-build-cache-extension/maven-build-cache-config.xml]
with modification to disable remote cache).
