Maven: report declared dependencies as direct in static analysis - #1770
Maven: report declared dependencies as direct in static analysis#1770csasarak wants to merge 9 commits into
Conversation
The static pomxml strategy returned Pom.analyze' un-shrunk: buildProjectGraph marks the project's own coordinate as the sole direct node, so every static Maven analysis reported the project artifact as the only Direct dependency and demoted every declared dependency to Transitive. Hosted imports (GitHub App / Quick Import) only ever run static analysis, so Auto PRs found nothing to upgrade on any Maven project. Apply the same treatment as the dynamic path: mark all first-party artifacts (the toplevel package plus submodules, mirroring buildGraph's knownSubmodules handling) as roots, then shrinkRoots removes them and promotes their declared dependencies to direct. Adds checked-in minimal single-module and multi-module repro fixtures and a spec that runs the real static entry point (getDepsStatically) against them.
- Changelog: describe static path as hosted imports plus dynamic-analysis fallback, not only 'mvn unavailable'. - getStaticAnalysis comment: parenthesize the first-party set for readability. - StaticAnalysisSpec: note that the raw Pom.analyze' invariant test is coupled to buildProjectGraph and should be updated in tandem with it.
Extract the shared 'apply filters then shrinkRoots' tail into finalizeMavenGraph so both dynamic and static paths use the same code, preventing the two from drifting apart again (the root cause of the project-artifact-as-sole-direct-dep bug). Behavior-identical per reviewer request; all 78 Maven unit tests pass.
The promote-first-party-then-shrink predicate was inlined in getStaticAnalysis; Strategy.Scala's pom fallback needs the identical step, so share it (also lifts depNameFromMavenDependency out of filterMavenSubmodules' where-block). Behavior-neutral for Maven. Scala is next; Maven and Scala specs guard this.
analyzeWithPoms was the last resort in Scala's getDeps chain (dependency-tree JSON <||> dependencyTree <||> poms). The two sbt-native tactics already shrink roots; the pom fallback returned Pom.analyze' un-shrunk, so any analysis that degraded to it reported the project's own artifact as the sole Direct dependency and demoted every declared dependency to Transitive -- the same shape as the Maven static bug this branch fixes. Apply the shared promoteFirstPartyToDirect + shrinkRoots, add a checked-in real sbt project (pom-fallback-repro, MiniDependencyTreePlugin disabled so discovery forces the fallback) plus its verbatim makePom output as the unit-test fixture, and pin analyzeWithPoms' graph shape via Scala.PomFallbackSpec (newly exported for the test, precedent: getDepsStatically). Verified: pre-fix binary reports the project artifact as sole Direct on pom-fallback-repro; post-fix it reports the pom's declared deps (scala-library, cats-core) with the artifact removed, matching the sbt-native tactics modulo the expected complete-vs-partial breadth gap.
…lback comment" This reverts commit a8be64e.
WalkthroughMaven analysis now shares graph finalization between static and dynamic paths. The finalization promotes external dependencies of first-party modules and removes first-party roots. Scala POM fallback applies the same dependency classification before graph conversion. New Maven and Scala regression tests use checked-in project fixtures. The test suite registers both modules. The changelog adds release 3.18.3 and normalizes historical formatting and URLs. Merge Risk: 🔵 Low · up to Maven static and Scala POM-fallback analysis now classify declared external dependencies as direct and omit first-party artifacts. The functional coverage is present, but two changelog links are broken and the new Haskell code does not meet required import and formatting conventions, leaving low merge-readiness risk. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Claude found a reasonably important bug, so I'm requesting changes. I think it's fine once that is fixed, though
| - Maven: static analysis (`pomxml`, used for hosted imports such as GitHub App / Quick Import and as the fallback when dynamic analysis is unavailable) no longer reports the project's own artifact as the only Direct dependency with every declared dependency demoted to Transitive; the static path now removes the project artifact and promotes declared dependencies to Direct, matching dynamic analysis. | ||
| - Scala: the sbt-generated-pom fallback no longer reports the project's own artifact as the only Direct dependency; it now removes the project artifact and promotes declared dependencies to Direct, matching Scala's dependency-tree tactics. | ||
| - Dart: `pubspec.yaml` files using valid dependency forms the parser previously rejected no longer fail analysis with `Aeson exception: ... empty` or `failed parsing pub package's source!`: a bare dependency with no value (any version), a `version:`-only entry, the `hosted: <url>` shorthand introduced in Dart 2.15, a `hosted:` map without a `version`, and a `git:` map without a `ref`. ([#1760](https://github.com/fossas/fossa-cli/pull/1760)) | ||
| - Workflows: `fossa analyze --x-workflow <path>` runs a dependency-usage workflow analyzer through the embedded ficus and records its result in the debug bundle. ([#1761](https://github.com/fossas/fossa-cli/pull/1761)) |

Should this be added back in?

Also, were the whitespace changes intentional? They're reasonable - it's nice to have a space after every header. But it adds a lot of change to the Changelog that will be linked to this PR

Claude noticed that we double-shrink if you scope dependencies with scope-only, resulting in no dependencies being found
Repro is a .fossa.yml like this:
# .fossa.yml
version: 3
maven:
scope-only:
- compile
And a pom.xml like this:
<project xmlns="http://maven.apache.org/POM/4.0.0">
<modelVersion>4.0.0</modelVersion>
<groupId>com.example</groupId>
<artifactId>app</artifactId>
<version>1.0.0</version>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.13.2</version>
<scope>compile</scope>
</dependency>
</dependencies>
</project>
And run with --static-only-analysis:
fossa-dev analyze --output --static-only-analysis | jq .sourceUnits
I see no imports in my source units. I see one source unit if I run on main.
Here's more info from Claude:
Adding shrinkRoots to the static path double-shrinks when experimental.maven.scope-only is set. filterMavenDependencyByScope (Common.hs) uses Graphing.shrink, which rewires through deleted vertices. First-party nodes have empty dependencyScopes — only addDep attaches MavenLabelScope, never buildProjectGraph's direct (coordToPackage ...) — so under MavenScopeIncludeFilters with a non-empty set they hit the (True, False) branch and are excluded. shrink then rewires Root → project → dep into Root → dep, promoting declared deps to direct itself.
shrinkRoots then deletes that promoted layer. Because static pom graphs are only two levels deep (declared deps are leaves), shrinkSingle finds an empty postSet and there is nothing to promote:
Root → project → junit -- scope include filter removes `project`
Root → junit -- ...then shrinkRoots removes `junit`
Root -- empty graph
So with scope-only: [compile] and a compile dep, --static-only-analysis now reports nothing where it previously reported the dep. Exclude filters are unaffected (empty scopes hit (True, _) → True).
The dynamic path has the same latent flaw — but there it only loses the direct layer while transitives survive, since those graphs have real depth. This PR imports it into static, where it's total data loss.
Fix is probably to exempt first-party nodes from scope filtering (they have no scope to filter on), e.g. keep any node whose name is in submoduleSet in isMavenDependencyIncluded. That would fix the dynamic path at the same time.
2 participants
Our static pom.xml strategies always marked every dependency beside the project itself as a transitive dependency. We never seem to have noticed because for a lot of our product it doesn't really matter that much: you have to comply with the license or address the security issues regardless of where in the project graph the dep appears.
That is not true for some product areas now. This PR changes our static pom.xml strategies to correctly label dependencies in the graph.

It's pretty easy to see this with most Maven projects. I used one from our example-projects repo.

Note the way we cache builds may affect this if you go to test. After it releases that shouldn't be a problem after a day or so.
Risks
If customers have workflows that are based on the broken behavior this may change the work they have to do - I could see scenarios where it is more and also scenarios where it's less.
