You don't seem to have enough free space to install Java, which is
|
|
needed by several components we install (ADTPro and AppleCommander,
|
|
for example.) On a Raspberry Pi, it is possible that you may simply
|
|
need to expand your filesystem to fill the SD card. You can do that
|
|
by running "sudo raspi-config" and selecting the appropriate option.
|
|
|
|
If that's not the cause, you might investigate to see if you happen
|
|
to have unwanted large packages installed. Some systems come loaded
|
|
with full desktop environments, development IDEs, or other large
|
|
packages or package groups you don't need.
|
|
|
|
Failing all of that, you can figure out how to get java installed and
|
|
into your default path and set JAVA_HOME. If we find java in your
|
|
path this script will assume that we should simply use that. We do
|
|
recommend Java 8 or above.
