Build dependencies (7.x Beta)

7.x Beta

Build-dependencies capture is new in 7.x. The Gradle plugin walks the resolved classpath at task execution and uploads a normalised DFS-ordered list. The same blob feeds Bugsee's vulnerability scan, so capturing dependencies is also the gate for OSV-backed CVE reporting.

What gets captured

The plugin's DependencyCollector resolves a Gradle configuration (runtime by default), walks it in depth-first pre-order, and emits a DependencyEntry for every node:

Field	Meaning
id	Stable identifier — group:name:version for libraries, project path for project deps, file name for file deps
group / name / version	Maven coordinates (library entries only)
direct	true if the entry is in your build.gradle directly; false for transitive entries
scope	The configuration the entry was resolved from (e.g. "runtime")
type	"library" (Maven artefact), "project" (multi-module project dep), "file" (local jar/aar)
parents	The list of ids that pulled this entry in — useful for "why is this here?" debugging
selected_reason	Gradle's resolution reason string (e.g. "between versions 1.2 and 1.4 chose 1.4 by conflict resolution"); only populated when explicitly requested via DSL
ecosystem	Always "maven" on library entries — required so the vulnerability scanner can query OSV against the correct package universe

The walk is bounded by maxCount (default 5000); entries past the cap are dropped and the upload is flagged truncated: true.

What gets uploaded

The inline dependencies_summary is a top-level key on the build POST body — a compact aggregate that always ships with the build POST:

{
  "total": 312,
  "direct": 24,
  "transitive": 288,
  "by_type": {
    "library": 296,
    "project": 12,
    "file": 4
  },
  "truncated": false,
  "collected_at": "2026-06-10T14:30:00Z",
  "collection_config": {
    "scope": "runtime",
    "include_selected_reason": false,
    "max_count": 5000
  }
}

The detail blob — gzipped JSON — is shipped to a separate presigned PUT URL when dependencies.enabled is true:

{
  "schema_version": 1,
  "truncated": false,
  "collection_config": { "scope": "runtime", "include_selected_reason": false, "max_count": 5000 },
  "dependencies": [
    {
      "id": "androidx.compose.ui:ui:1.6.4",
      "group": "androidx.compose.ui",
      "name": "ui",
      "version": "1.6.4",
      "direct": true,
      "scope": "runtime",
      "type": "library",
      "ecosystem": "maven",
      "parents": []
    }
  ]
}

The collection_config block is captured on every blob so the worker's diff logic can refuse to compare apples-to-oranges: a build collected with max_count=5000 is never diffed against one collected with max_count=1000.

Configuration

build.gradle.kts

bugsee {
    buildInfo {
        dependencies {
            // Enable the upload of the gzipped detail blob (and
            // therefore the dashboard's per-dependency table and
            // the vulnerability scan). The inline summary always
            // ships when `buildInfo.enabled` is true.
            // Default: true.
            enabled.set(true)

            // Gradle configuration to walk. Default: "runtime".
            // Use "compileClasspath" or a custom configuration name
            // to capture compile-only or annotation-processor deps.
            // scope.set("runtime")

            // Include Gradle's `selectedReason` string on each
            // entry. Useful for diagnosing version-conflict
            // resolution but bloats the blob significantly.
            // Default: false.
            // includeSelectedReason.set(false)

            // Hard cap on entries. Entries past the cap are
            // dropped and `truncated: true` is set on the blob.
            // Default: 5000.
            // maxCount.set(5000)
        }
    }
}

build.gradle

bugsee {
    buildInfo {
        dependencies {
            enabled.set true                  // default: true
            // scope.set 'runtime'             // default: 'runtime'
            // includeSelectedReason.set false // default: false
            // maxCount.set 5000               // default: 5000
        }
    }
}

What you see in the dashboard

The build detail page's Dependencies tab is rendered when dependencies_status == 'ready'. Two parts:

Stat chip strip

Across the top: Total, Direct, Transitive, Library, Project, File. When truncated is true, a warning chip appears so the cap doesn't silently hide the tail.

When the worker job is still in flight, a status pill replaces the chips — uploading (blob in transit), processing (worker normalising and diffing), or failed (schema mismatch / oversize / S3 transient).

Vulnerability strip

The Dependencies tab is also where Bugsee's vulnerability findings show up — see the dedicated Vulnerabilities page for the details. The strip renders between the chip row and the table whenever vuln_scan_summary is populated.

Per-dependency table

A scrollable, sortable, filterable table listing every captured entry. Columns: id, direct/transitive, type, parents count, and (when present) selected_reason. Click a row to expand the full parents path — useful for tracing "why is this transitive dep here?" through the import graph.

Worker pipeline

The S3 ObjectCreated event for the uploaded dependencies blob is routed to jobs.dependencies.Process on the Bugsee worker. The pipeline mirrors timings: bootstrap PATCH (dependencies_status='processing') → download with cap (32 MiB inflated, 100 000 entries) → validate schema_version → re-upload the gzipped bytes to the per-build S3 prefix → run a diff vs the previous build (gated on identical collection_config so the diff stays meaningful) → final PATCH (dependencies_ref, dependencies_status='ready').

When dependencies_status flips to 'ready', the worker also enqueues the vulnerability scan job for the same build — vulnerabilities are derived from the dependencies list, so the scan can't run before the dependencies blob lands.
