In @.gitignore:
- Line 27: Update the .mcrun-state.json entry in .gitignore to use an unanchored
pattern, ensuring generated state files are ignored in nested server directories
as well as the repository root.
In `@internal/config/config_test.go`:
- Line 62: Check the return value of each os.WriteFile call in the config tests
and fail the current subtest when fixture creation fails. Apply this to
internal/config/config_test.go lines 62, 75, and 89; use the test’s existing
subtest error-reporting mechanism and leave the fixture contents unchanged.
In `@internal/config/config.go`:
- Line 183: Reject negative numeric configuration values by requiring positive
values at all default-selection sites: in internal/config/config.go lines 183
and 189, update the local Java version checks; in cmd/mcrun/root.go line 97,
update the cfg.Java.Version check; and in cmd/mcrun/run.go lines 79, 82, and 85,
update the network.Port, network.QueryPort, and network.RconPort checks
respectively. Preserve the existing behavior for positive configured values and
apply defaults for zero or negative values.
In `@internal/java/installer.go`:
- Around line 63-68: Update the temporary archive setup after archive.Name() so
archive.Close() errors are handled, then remove the placeholder archive before
DownloadFile runs. Return descriptive errors for close or removal failures and
preserve cleanup of archivePath with deferred removal.
In `@internal/server/runner.go`:
- Around line 98-99: Add an explicit nilerr suppression comment to the ctx.Err()
early-return branch in the runner's preparation error handling, documenting that
a requested stop intentionally returns nil; preserve the existing behavior and
avoid changing other error paths.
In `@internal/utils/env.go`:
- Around line 49-50: Update JavaEnvironment’s explicit Java path handling to
resolve symlinks with filepath.EvalSymlinks before deriving JAVA_HOME, while
preserving direct execution of the selected binary. Derive JAVA_HOME from the
resolved installation path rather than the unresolved path returned by
GetByPath.

Remove the placeholder archive before DownloadFile.
os.CreateTemp leaves archivePath in place. On Windows, Go 1.25 implements os.Rename with MoveFileW, which rejects an existing destination. Therefore, DownloadFile fails when it renames archivePath+".tmp" to archivePath.
Proposed fix
archivePath := archive.Name()
- archive.Close()
+ if err := archive.Close(); err != nil {
+ os.Remove(archivePath)
+ return nil, fmt.Errorf("failed to close temporary archive: %w", err)
+ }
+ if err := os.Remove(archivePath); err != nil {
+ return nil, fmt.Errorf("failed to prepare temporary archive path: %w", err)
+ }
