             Summary: Unable to unpack maven index on Linux
                 Key: NETBEANS-210
                 URL: https://issues.apache.org/jira/browse/NETBEANS-210
             Project: NetBeans
          Issue Type: Bug
          Components: projects - Maven
    Affects Versions: 9.0
         Environment:   Product Version         = Apache NetBeans IDE Dev (Build 20171212-unknown-revn)
  Operating System        = Linux version 4.9.0-4-amd64 running on amd64
  Java; VM; Vendor        = 1.8.0_151; OpenJDK 64-Bit Server VM 25.151-b12; Oracle Corporation
  Runtime                 = OpenJDK Runtime Environment 1.8.0_151-8u151-b12-1~deb9u1-b12
  Java Home               = /usr/lib/jvm/java-8-openjdk-amd64/jre
  System Locale; Encoding = es_ES (nb); UTF-8

  Cache Directory         = /home/antonio/.cache/netbeans/dev
            Reporter: Antonio Vieiro
            Priority: Blocker
         Attachments: maven-1.png, maven-2.png, maven-exception.txt

In Linux the system property "java.io.tmpdir" is set to "/tmp" by default.
In modern Linux distributions (Debian 9, Ubuntu?) the "/tmp" filesystem is only a few gigabytes big. In my case "df -h" reports:

{code}
/dev/sda5        1,9G    12M  1,7G   1% /tmp
{code}

These "1.9G" of total size are not big enough to unpack the maven index, so NetBeans *always* fails to unpack the maven index, and cannot run Maven based projects.

A solution to the problem could be adding 

{code}
-Djava.io.tmpdir=[netbeans_user_directory]/tmp
{code}

at startup, adding it to [netbeans_installation_directory]/etc/netbeans.conf
