[bug#47789] [PATCH 6/6] gnu: Add tla2tools.

[Mike Gerwitz <mtg@gnu.org>]

[-- Attachment #1: Type: text/plain, Size: 13805 bytes --]

This introduces tla2tools.jar, which contains the TLA+ model checker
and simulator (TLC); a TLA+ REPL; a semantic analyzer (SANY); the TLATeX
typesetting system; PlusCal translator; and more.  I have added five
wrapper scripts for convenience, rather than invoking `java' manually.
The wrapper scripts are not comprehensive; users who are familiar with
tla2tools.jar, or have read the book Specifying Systems, may still
invoke the commands in the traditional way.

The minimum JDK version is 11.  I chose to stick with that rather than
bumping it to 14 (which is the largest version currently in Guix)
because each OpenJDK version in Guix depends on the version before it,
and so it needlessly results in many 100s of MiB of unnecessary
dependencies.

Note that this is _not_ the TLA+ Toolbox, which is the GUI commonly used
with TLA+.

* gnu/packages/java.scm (tla2tools): New variable.
* gnu/packages/patches/tla2tools-build-xml.patch: New patch.

+tla2tools comes packaged with three separate javax.mail JARs, which it
+expects to be available to include in the JAR produced by the `dist' target.
+However, the `java-javax-mail' packaged with Guix contains all of these
+dependencies in a single JAR, so the other two are unneeded.  This patch
+removes references to them.
+
+The JAR also was expected to contain classes that are built as part of the
+test suite.  That does not seem useful, nor is it available during the
+`compile' phase, so that portion is removed.
+
+There are a number of Git attributes that are set in the final manifest.
+The branch name is kept, but the others are removed.  The build user is set
+statically to "guix".
+
+Finally, since we already have a patch, two targets `jar' and `check' are
+added to satisfy `ant-build-system' and keep the package definition more
+lean.
