Run tests in localeTest and read bucket quota from size

[allanrogerr]

Description

• build.gradle: the localeTest task now takes testClassesDirs and classpath from the test source set, so it runs the unit tests under locale de-DE instead of reporting NO-SOURCE. The testLogging settings now apply to every Test task, so a failure in localeTest prints the expected and actual values and the stack, like test does.
• MinioAdminClient: getBucketQuota now reads the limit from size, and setBucketQuota sends size, as madmin-go v4's BucketQuota does. The client no longer reads or sends the deprecated quota key.

Motivation and Context

• localeTest runs as part of build. Since upgrade dependencies #1698 moved the Gradle wrapper from 8.14.3 to 9.4.1, it reports NO-SOURCE for api and adminapi and runs no tests.
• AIStor RELEASE.2026-09-07T08-39-31Z returns the bucket quota as {"size":1048576,...} with no quota key. On master, getBucketQuota throws quota not found in response for every existing bucket on that server, including after the quota is cleared.
• MinioAdminClient follows the current server API and is not backward compatible by design. Servers whose madmin-go has the size field (added in August 2023) accept and return size, including AIStor RELEASE.2024-12-31T04-11-53Z and MinIO RELEASE.2025-09-07T16-13-09Z.

How to test this PR?

Environment: Temurin JDK 25.0.4.1; servers started with root user minio / minio123: AIStor quay.io/minio/aistor/minio:latest RELEASE.2026-09-07T08-39-31Z, AIStor RELEASE.2024-12-31T04-11-53Z, and MinIO quay.io/minio/minio:latest RELEASE.2025-09-07T16-13-09Z.

1. Run ./gradlew :api:localeTest --rerun :adminapi:localeTest --rerun.
2. Run ./gradlew :adminapi:shadowJar, compile QuotaProbe (below) with javac -cp adminapi/build/libs/minio-admin-9.0.4-DEV-all.jar -d probe QuotaProbe.java, then run java -cp probe:adminapi/build/libs/minio-admin-9.0.4-DEV-all.jar QuotaProbe http://127.0.0.1:9000. The probe sets a 1 MiB quota, reads it, clears it and reads it again, and prints each quota response.

Older servers (QuotaProbe results; master sets and reads quota, this branch sets and reads size):

server	master: after set / after clear	this branch: after set / after clear
AIStor RELEASE.2024-12-31T04-11-53Z	1048576 / 0	1048576 / 0
MinIO RELEASE.2025-09-07T16-13-09Z	1048576 / 0	1048576 / 0

Other checks:

• ./gradlew build and ./gradlew build -Prelease pass on this branch, including Spotless, SpotBugs and localeTest.
• With one failing unit test, ./gradlew build stops at localeTest; that output now shows expected:<...> but was:<...> and the stack.

📝 Walkthrough

Walkthrough

The bucket quota API now sends and reads the size field. Unit and functional tests cover quota operations and validation. The localeTest task now uses compiled test classes and its runtime classpath.

Changes

Bucket quota compatibility

Layer / File(s)	Summary
Bucket quota API and unit tests adminapi/src/main/java/io/minio/admin/MinioAdminClient.java, adminapi/src/test/java/io/minio/admin/MinioAdminClientTest.java	setBucketQuota sends size, and getBucketQuota reads size. Tests cover valid, zero, missing, non-integral, fractional, and out-of-range values.
Functional quota validation functional/TestMinioAdminClient.java	The functional test creates a bucket, sets a 1 MB quota, verifies the quota, clears it, verifies zero, and removes the bucket.
Test execution wiring build.gradle	Test logging applies to all Test tasks. localeTest uses the default test output directories and runtime classpath.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: ⚪ Minimal · up to ff764

verify quota.canConvertToLong() before calling quota.longValue(), preventing
out-of-range values from being treated as zero; add a regression test for an
oversized size with quota 2048 that expects MinioException.
