Netbeans can't update index file due to lack of space

[retog]

Getting message. there is not enough space in your temp folder to download and unpack the index for 'sonatype-oss-repository'

[retog]

Tried mounting /tmp from the host where there's a lot of free space but the problem persists

I recommend using a plugin to access the index online, having this index offline isn't really useful.
