After your last message, Alex, I saw the issue on a branch with minimal unrelated changes on top of b4b5495307 <https://github.com/apache/beam/commit/b4b549530730d9e0283ad0cdb203d384a107dfbf> (January 28).
I ran `./gradlew clean` for the first time in a while at that time, and worked happily for 11 days, but just saw the issue again on a branch rebased on top of 381ab55b59 <https://github.com/apache/beam/commit/381ab55b59> (today): > Task :beam-sdks-java-extensions-sql:compileJava FAILED …/sdks/java/extensions/sql/src/main/java/org/apache/beam/sdk/extensions/sql/impl/JdbcFactory.java:29: error: cannot find symbol import org.apache.beam.sdk.extensions.sql.impl.parser.impl.BeamSqlParserImpl; ^ symbol: class BeamSqlParserImpl location: package org.apache.beam.sdk.extensions.sql.impl.parser.impl 1 error Every time I've seen it, I immediately re-run the compile, and it succeeds. Perhaps something is still wrong with my environment, but otherwise it would seem that something is still flaky here. I'm compiling on an 8-core macOS machine, fwiw, and usually running `./gradlew compileTestJava` which compiles many projects concurrently.
