This wraps each command executed by CMake with a wrapper that
generates a JUnitXML file if the command fails. If the command
succeeds, the wrapper does nothing. The wrapper applies to C++
compilation, linking, and custom shell commands (such as
building the frontend via maven). It does not apply to failures
coming from CMake itself. It can be disabled by setting
DISABLE_CMAKE_JUNITXML.
The command output can include Unicode (e.g. smart quotes for
g++), so this also updates generate_junitxml.py to handle
Unicode.
The wrapper interacts poorly with add_custom_command/add_custom_target
CMake commands that use 'cd directory && do_something', so this
switches those locations (in /docker) to use CMake's WORKING_DIRECTORY.
Testing:
- Verified it does not impact a successful build (including with
ccache and/or distcc).
- Verified it generates JUnitXML for C++ and Java compilation
failures.
- Verified it doesn't use the wrapper when DISABLE_CMAKE_JUNITXML
is set.
