 <p>It's possible to build both Windows and Linux binaries from WSL. To build Windows binaries, you must use a Windows boot JDK (located in a Windows-accessible directory). To build Linux binaries, you must use a Linux boot JDK. The default behavior is to build for Windows. To build for Linux, pass <code>--build=x86_64-unknown-linux-gnu --host=x86_64-unknown-linux-gnu</code> to <code>configure</code>.</p>
 <p>If building Windows binaries, the source code must be located in a Windows- accessible directory. This is because Windows executables (such as Visual Studio and the boot JDK) must be able to access the source code. Also, the drive where the source is stored must be mounted as case-insensitive by changing either /etc/fstab or /etc/wsl.conf in WSL. Individual directories may be corrected using the fsutil tool in case the source was cloned before changing the mount options.</p>

To use a specific version of Xcode, use <code>xcode-select -s</code> before running <code>configure</code>, or use <code>--with-toolchain-path</code> to point to the version of Xcode to use, e.g. <code>configure --with-toolchain-path=/Applications/Xcode8.app/Contents/Developer/usr/bin</code></p>

+The JCov report is stored in `build/$BUILD/test-results/jcov-output`.

-While collecting code coverage with JCov, it is also possible to find coverage
-for only recently changed code. JCOV_DIFF_CHANGESET specifies a source
-revision. A textual report will be generated showing coverage of the diff
-between the specified revision and the repository tip.
