Note

Medium Risk
Besu 26.7.0 touches core execution/client dependencies across the stack; risk is moderate though mitigated by targeted Gradle clean fixes and small test HTTP API adjustments.

Overview
Bumps the monorepo to Hyperledger Besu 26.7.0 by updating besuCommit in gradle/libs.versions.toml and the cached linea-besu/besu/.besu-resolved mapping (26.7.0-f036a17). Local docker defaults now pin a newer coordinator image tag.

Gradle/build ergonomics so clean no longer kicks off a long on-demand Besu build: :linea-besu:besu skips buildAndPublishBesuAction when only clean task(s) are requested, and maru’s jar manifest computes Class-Path lazily via a Provider instead of resolving runtimeClasspath at configuration time. Coordinator and transaction-exclusion-api jar manifests now filter dependencies with endsWith('.jar'). .gitignore targets linea-besu/besu/.besu-resolved.

Acceptance tests drop unnecessary !! on OkHttp response.body when parsing Engine API JSON (aligned with updated APIs in the Besu 26.7 test stack).

Pull request overview

This PR updates the pinned Hyperledger Besu source revision used by the linea-besu build (via the Gradle version catalog) to target Besu v26.7.0, which affects how Besu artifacts are resolved/built for downstream Linea Besu modules and CI workflows.

Changes:

• Bump besuCommit in gradle/libs.versions.toml to f036a1738493f52999e931e9a61d9a065b749603 (annotated as 26.7.0).

gradle/libs.versions.toml:45

• besuCommit is described as the single source of truth for the Besu version. Adding a separate # Besu version: ... comment creates a second manual sync point that can drift on future bumps unless it is updated by automation.

# Besu version: 26.7.0
besuCommit = "f036a1738493f52999e931e9a61d9a065b749603"

• This header says the file is gitignored, but the repository ignore rule currently targets /linea-besu/.besu-resolved (see .gitignore:188), not linea-besu/besu/.besu-resolved. This is misleading, especially since CI force-adds this path.

# Do NOT edit by hand and do NOT commit local changes — this file is gitignored.

• The header comment says this file is gitignored, but the repo’s .gitignore only ignores /linea-besu/.besu-resolved (not linea-besu/besu/.besu-resolved), and CI explicitly force-adds this path. This comment is misleading for contributors and reviewers when investigating why the file is tracked/updated.

linea-besu/besu/.besu-resolved:6

• .besu-resolved is intended to be gitignored (per the header comments and .github/workflows/linea-besu-build-and-publish.yml), but the repo’s .gitignore currently ignores /linea-besu/.besu-resolved (different path) rather than linea-besu/besu/.besu-resolved. This mismatch can cause locally regenerated cache changes to be staged accidentally and makes the workflow comment misleading.

Suggested fix: update .gitignore to ignore linea-besu/besu/.besu-resolved (or adjust the cache file location/workflow if the current ignore path is intentional).

• assertBlockImportRejected consumes the OkHttp response body but never closes the Response. The current call sites (BlobTransactionBlockImportDenialTest, EIP7702TransactionBlockImportDenialTest) also don’t wrap the response in .use {}. This can leak connections/file descriptors and cause flaky tests. Consider closing the response inside this helper via response.use { ... }.

  protected fun assertBlockImportRejected(response: Response, expectedValidationError: String) {
    val result = mapper.readTree(response.body.string()).get("result")
    val status = result.get("status").asText()
    val validationError = result.get("validationError").asText()
    assertThat(status).isEqualTo("INVALID")
    assertThat(validationError).contains(expectedValidationError)
  }

• okhttp3.Response.body is nullable with OkHttp 4.12.0, so getPayloadResponse.body.string() won’t compile. Unwrap the body explicitly before calling .string().

• okhttp3.Response.body is nullable with OkHttp 4.12.0, so newPayloadResponse.body.string() won’t compile. Unwrap the body explicitly before calling .string().

        .readTree(newPayloadResponse.body.string())

maru/app/build.gradle:119

• Manifest.attributes expects concrete values; passing a Provider as the Class-Path value risks serializing the Provider’s toString() into the manifest instead of the computed classpath. Resolve the provider inside a doFirst { ... } so it’s evaluated during task execution (and still avoids runtimeClasspath resolution on clean).

  manifest {
    attributes(
        'Class-Path': classPathAttribute,
        'Main-Class': 'maru.app.CliEntrypoint',
        'Multi-Release': 'true'
        )
  }
