+# Note: to bump sbt, some things to try are:
+# 1. remove the https://dev.gentoo.org/~gienah/snapshots/${P}-ivy2-deps.tar.xz
+# https://dev.gentoo.org/~gienah/snapshots/${P}-sbt-deps.tar.xz and
+# binary? ( https://dev.gentoo.org/~gienah/files/dist/${P}-gentoo-binary.tar.xz )
+# from SRC_URI
+# 2. Comment the sbt publishLocal line in src_compile.
+# 3. try:
+# FEATURES='noclean -test' emerge -v -1 dev-java/sbt
+# It should fail in src_install since the sbt publishLocal is not done.
+# Check if it downloads more stuff in
+# src_compile to ${WORKDIR}/.ivy2 and ${WORKDIR}/.sbt.
+# 4. If some of the downloads fail, it might be necessary to run the sbt compile
+# again manually to obtain all the dependencies, if so:
+# cd to ${S}
+# export EROOT=/
+# export WORKDIR='/var/tmp/portage/dev-java/${P}/work'
+# export L_P=${P}
+# export PATH="${WORKDIR}/${L_P}:${PATH}"
+# sbt compile
+# cd ${WORKDIR}
+# find .ivy2 .sbt -uid 0 -exec chown portage:portage {} \;
+# 5. cd ${WORKDIR}
+# XZ_OPT=-9 tar --owner=portage --group=portage \
+# -cJf /usr/portage/distfiles/${P}-ivy2-deps.tar.xz .ivy2/cache
+# XZ_OPT=-9 tar --owner=portage --group=portage \
+# -cJf /usr/portage/distfiles/${P}-sbt-deps.tar.xz .sbt
+# Uncomment the sbt publishLocal line in src_compile.
+# 6. It *might* download more dependencies for src_test, however the presence
+# of some of these may cause the src_compile to fail.  So download them
+# seperately as root so we can identify the
+# additional files.  As root:
+# cd ${S}
+# ${S}/${P} test
+# cd ${WORKDIR}
+# XZ_OPT=-9 tar --owner=portage --group=portage \
+# -cJf /usr/portage/distfiles/${P}-test-deps.tar.xz \
+# $(find .ivy2/cache .sbt -uid 0 -type f -print)
+# Note: It might not download anything in src_test, in which case
+# ${P}-test-deps.tar.xz is not required.
+# 7. Create the binary
+# cd $WORDKIR
+# XZ_OPT=-9 tar --owner=portage --group=portage \
+# -cJf /usr/portage/distfiles/${P}-gentoo-binary.tar.xz ${P} .ivy2/local
+# 9. Undo the earlier temporary edits to the ebuild.
