Installing Artifactory on Ubuntu

Posted on by jamesbetteley

I was messing around with some permissions settings on our “Live” verison of Artifactory, as you do, and then suddenly I thought “No! This feels wrong… I’m sure there’s someone who would be having a fit right now if he knew I was guffing around with the permissions on the live version of Artifactory…”. That someone is of course me. So I duly pressed cancel, and decided to do things “properly”, i.e. install a local version of Artifactory and mess around with that one instead.

Easier said than done.

How NOT to Install Artifactory on Ubuntu

If you want to know how to install Artifactory on Ubuntu, I’d suggest skipping to the “How to Install Artifactory on Ubuntu” section, below. However, if you’d love to know exactly how to NOT install Artifactory on Ubuntu while following the Artifactory installation instructions and getting really annoyed, then read on!

I decided to install it on my Ubuntu VirtualBox VM, because surely that would be easier than installing it on my Windows box, right? My Ubuntu VM is running java 1.7. So I downloaded the artifactory zip and extracted it. Dead easy! Then I followed this particular instruction on the artifactory installation webpage:

Before you install is recommended you first verify your current environment by running artifactoryctl check under the $ARTIFACTORY_HOME/bin folder

But by default it wasn’t executable, so I had to chmod it, duuuuh! So I did that, ran it, and I got the following error:

ARTIFACTORY_HOME not set

Er, well, no, I haven’t set ARTIFACTORY_HOME, that’s true. I had no idea I had to set it anywhere. So I set it in my profile, sourced it, and all that stuff.

I ran the artifactoryctl check command again and got another message saying:

Cannot find a JRE or JDK. Please set JAVA_HOME to a >=1.5

But that’s rubbish! I totally have 1.7 installed!! I checked my paths and all the rest. All looked fine to me. After a little while I got bored of seeing that exact same message, so I decided to just stop bothering with this stupid “artifactoryctl check” thing, and just moved on with the installation by running the $ARTIFACTORY_HOME/bin/install.sh script

ffs!

Gah! Not logged in as root. Sudo sudo sudo.

That’s better. I got a little message saying “SUCCESS” which was nice, followed by:

Installation of Artifactory completed. You can now check installation by running:

> service artifactory check

Okey dokey then, I’ll go do that!

Gahh!!! SUDO MAKE ME A SANDWICH!!!

Sudo !! is probably my most frequently typed command, along with “ll” (swiftly followed by “ls -a” when I realsie the ll alias hasn’t been setup. I’m an idiot, ya’see).

Anyway, following a swift sudo !! I got the following message:

Found JAVA= in JAVA_HOME=

Cannot find a JRE or JDK. Please set JAVA_HOME to a >=1.5 JRE

Erm, I’m pretty sure that’s not right. I definitely remember installing Java 1.7 and setting JAVA_HOME. So I echoed JAVA_HOME. Sure enough, it’s pointing to my 1.7 installation path.

Turns out that setting it in my bash profile wasn’t good enough, and I had to also put it in the following file:

/etc/artifactory/default

Oh, and don’t put the symlink path in for JAVA_HOME, that didn’t work. I had to put the full path in (/usr/bin/java got me nowhere). I literally had to put the full location in (mine was /usr/lib/jvm/java-7-openjdk-amd64/jre/). Anyway, that just about did it. Piss easy!

How to Install Artifactory on Ubuntu

  • Make sure you’ve got Java 1.5 or above installed, and make a note of the full path, as you’re going to need this later (mine was /usr/lib/jvm/java-7-openjdk-amd64/jre/).
  • Download the artifactory zip and extract it somewhere.
  • Go to your artifactory bin dir and make the install.sh file executable
  • Now run sudo ./install.sh – this will copy some files around the place and setup some paths.
  • Edit the file /etc/artifactory/default and put the FULL Java path in there as JAVA_HOME
  • Make sure JAVA_HOME is also set in /etc/environment
  • run “sudo service artifactory check”
  • If it all looks good run “sudo service artifactory start”
  • Go to http://localhost:8081/artifactory/
  • You’re done!

Fixing java heap issue with maven sites

Posted on by jamesbetteley

I’ve suddenly started getting a few java heap (OutOfMemory) errors with my maven builds, mainly when I run the mvn site phase, but also sometimes when I run sonar:sonar.

I’m running the builds on both linux (centos) and windows.

To fix the issue on Windows:

Edit mvn.bat (this lives in your maven bin directory) and add

set MAVEN_OPTS=-Xmx512m

In theory you could add an environment variable called MAVEN_OPTS and give it the same value as above (Xmx512m) but this didn’t actually work very well for me.

To fix on linux:

Edit your mvn file (which for me was in /usr/local/maven/bin/) and add:

export MAVEN_OPTS=”-Xms256m -Xmx512m”

You could of course add this to your bash profile (don’t forget to source it afterward) or add it to etc/profile, but I found adding it to the mvn file to work best.

To fix on Continuous Integration Servers:

I’ve been getting this error on a number of our CI servers as well, so rather than go around adding “export MAVEN_OPTS” all over the place, I am passing it via the CI system. Hudson, Jenkins, Bamboo and Go all have simple UIs for adding extra parameters to your build commands.
