breun opened a new issue, #399:
URL: https://github.com/apache/maven-build-cache-extension/issues/399
### Affected version
1.2.0
### Bug description
The Maven Build Cache Extension works when lifecycle phases are executed,
but does not seem te be active when an additional plugin goal is executed (e.g.
`mvn verify dependency:tree`).
**Expected behavior**
When running `mvn verify dependency:tree` on a project that previously
stored its build result in the Maven build cache, I expect the cached result to
be restored.
**Actual behavior**
The previously cached result doesn't seem to be restored.
**Reproduction**
Here are the steps to reproduce this issue:
1. Create a simple Maven project called `my-app`.
```
❯ mvn archetype:generate \
-DarchetypeArtifactId=maven-archetype-quickstart \
-DarchetypeVersion=1.5 \
-DgroupId=com.example \
-DartifactId=my-app \
-Dversion=1.0.0-SNAPSHOT \
-DjavaCompilerVersion=21 \
-DinteractiveMode=false && cd my-app
```
2. Add the Maven Build Cache Extension.
```
❯ cat <<EOF > .mvn/extensions.xml
<extensions xmlns="http://maven.apache.org/EXTENSIONS/1.1.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://maven.apache.org/EXTENSIONS/1.1.0
https://maven.apache.org/xsd/core-extensions-1.1.0.xsd";>
<extension>
<groupId>org.apache.maven.extensions</groupId>
<artifactId>maven-build-cache-extension</artifactId>
<version>1.2.0</version>
</extension>
</extensions>
EOF
```
3. Build it for the first time, see the Maven Build Cache Extension storing
the result in the local cache.
```
❯ mvn verify
(...)
[INFO] Local build was not found by checksum 0b97f1d6be2b14ce for
com.example:my-app
(...)
[INFO] Saved Build to local file:
/Users/nbreunese/.m2/build-cache/v1.1/com.example/my-app/0b97f1d6be2b14ce/local/buildinfo.xml
(...)
```
4. Clean and build again, and see the cached artifacts getting restored:
```
❯ mvn clean verify
(...)
[INFO] Found cached build, restoring com.example:my-app from cache by
checksum 0b97f1d6be2b14ce
(...)
```
Up to here everything works as expected.
But now, when you run `verify` again, but add `dependency:tree` as an
additional plugin goal, the build cache doesn't seem to be used, because there
are no messages about restoring anything, and the tests are ran again:
```
❯ mvn clean verify dependency:tree
