Execution log

sbt 2.0.0 adds experimental execution log feature to debug caching issues. The execution log can be enabled with sbt.experimental_execution_log system property has either true or a file path:

$ sbt --server -Dsbt.experimental_execution_log=true compile

This will generate an execution log file in target/global-logging/exec-log****.log:
