Hello automakers.
Currently, Java support in Automake provides uninstall rules that doesn't
work after "make clean":
$ cat > configure.ac <<'END'
AC_INIT(x,0)
AM_INIT_AUTOMAKE(foreign)
AC_CONFIG_FILES(Makefile)
AC_OUTPUT
$ cat > Makefile.am <<'END'
javadir = $(prefix)/java
java_JAVA = foo.java
END
$ echo 'class Foo {}' > foo.java
$ autoreconf -vi
configure.ac:2: installing `./install-sh'
configure.ac:2: installing `./missing'
$ ./configure --prefix=/tmp
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
configure: creating ./config.status
config.status: creating Makefile
$ make
CLASSPATH=.:./.:$CLASSPATH javac -d . foo.java
echo timestamp > classjava.stamp
$ ls *.class
Foo.class
$ make install
/usr/bin/install -c -m 644 Foo.class '/tmp/java/'
$ make clean
rm -f *.class classjava.stamp
$ make uninstall
$ ls /tmp/java
Foo.class
While IMHO it's acceptable to provide uninstall rules that stop working
after "make distclean", having them broken by a simple "make clean" is
unacceptable.
Probably, the better fix is to write at "make all" time a file (to
be removed by "make distclean" only, not by "make clean") that lists
all the generated class files; then, at "make uninstall" time, that
that file can be used to recover the names of the files to uninstall.

Stefano
