Subject: Fix: Add versioning to liblttng-ust-agent JAR
X-Git-Tag: v2.7.0-rc1~78
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=85e091331484d860fc5f781e645341f37875b6ab;p=lttng-ust.git

Fix: Add versioning to liblttng-ust-agent JAR

The liblttng-ust-agent JAR need versioning. The manifest file contains the
appropriate information about the JAR, such as the current version.

A symlink is also created and installed in order to point to the latest
version of the JAR.

e.g: liblttng-ust-agent.jar -> liblttng-ust-agent-1.0.0.jar
