Updating eclipse 3 3 to 3 4
Important note: Java may be distributed in separate 32/64-bit packages.
Unless you have older applications requiring 32-bit Java, on 64-bit systems it is recommended to install the 64-bit JDK.
If you prefer to do this in more steps, go to the Eclipse packages and get the Eclipse IDE for C/C Developers archive appropriate for your platform, preferably the 64-bit version.
Links to older versions are available in the More Downloads section, at the bottom.
Do not try to install them on Mars, Luna, Kepler, Juno, Indigo, or older versions, since the install will fail.
The simple way is to download GNU MCU Eclipse IDE for C/C Developers from Git Hub Releases and you get at once both Eclipse CDT and the MCU plug-ins.
Starting with version 4.x, the oldest Eclipse supported by the plug-ins is Eclipse 4.6 Neon.3 (CDT 9.2), and the recommended version is 4.7 Oxygen.Note 2: Contrary to other tools, Eclipse does not need administrative rights, does need not be installed in a system location, and does not need not be a single instance on a system.
