Jul 1, 2025July 2025: Delivered three Bazel plugin enhancements for JetBrains/hirschgarten that strengthen import resolution, file lifecycle handling, and test readability, with full test coverage. Key features delivered: 1) Extension point for custom Python library lookup with integration into Bazel import resolution and new tests (commit 98d20e72aacf9780b8ef5105e631844844edc177, BA ZEL-2114). 2) Robust file event handling and improved mapping of files to Bazel targets/modules with expanded tests (commit f5a951f077f630a400f2a61ac31e6c43120541d0, BA ZEL-2191). 3) Cleaner JUnit5 test output by separating time from test names for readability (commit 93c99e6366b72a303584e729293ef308b5b1cf18, BA ZEL-2190). Major bugs fixed: improved file creation listener reliability and stabilized test feedback by removing time from test case names. Overall impact: higher reliability of import resolution, more accurate target mapping, and faster feedback cycles for developers. Technologies/skills demonstrated: Bazel plugin architecture, extension points, Java/JUnit5, test automation, event-driven file handling, and commit-level traceability.
