   Usage: ant [target]

+  The repository contains all dependencies except for ant and the JDK
+  itself.  Because the JDK version matters and because different
+  targets require different JDKs, we assume that users have created a
+  hierarchy containing:
+  $HOME/jdk/jdk11
+  $HOME/jdk/jdk12
+  $HOME/jdk/jdk13
+  $HOME/jdk/jdk14
+  $HOME/jdk/jdk15
+  $HOME/jdk/jdk16
+  where each of the above is a JDK or a symlink to same, and
+  $HOME/jdk/src/jdk11
+  $HOME/jdk/src/jdk12
+  $HOME/jdk/src/jdk13
+  $HOME/jdk/src/jdk14
+  $HOME/jdk/src/jdk15
+  $HOME/jdk/src/jdk16
+  where each of the above is a JDK source tree or a symlink to same.
+
+  Alternatively, define ant variables thus:
+  ant -Djdk$N.home=... -Djdk$N.src.home=...
+  for $N in 11 .. 16 ...
+
+  As of 2016-03, the sources in src/main are for jdk9+ only.
+  As of 2019-08, the sources in src/main are for jdk11+ only.
+  As of 2019-10, compatibility support for jdk8 is dropped entirely.
