Attempt on a common Vagrant instance.

Initial setup of Mediawiki-VagrantEdit

The usual setup is as described on MediaWiki-Vagrant, and yes you need Git

$ mkdir ~/ltspace
$ cd ~/ltspace
$ git clone --recursive .
$ ./
$ vagrant box update
$ vagrant up

Git updateEdit

At this point you should do a $ vagrant git-update in the host directory, otherwise you will probably run into problems later. Then do a $ vagrant reload to make sure everything works.

At this point you should clean up the client for outdated apt pakages. Do a

$ vagrant ssh
$ sudo apt-get update && sudo apt-get upgrade
$ sudo apt-get autoremove
$ exit

Note that this still leaves the box running old software, and you should do a sudo apt-get update && sudo apt-get upgrade from time to time.

Roles for the hostEdit

Use the following additional roles


This is the new visual editor, which would be the primary accesspoint for LanguageTool.

$ vagrant enable-role visualeditor && vagrant provision && vagrant git-update

Java in the guestEdit

Not clear if the version should be 7 or 8. Only thing I got to pass was Java 8 from Oracle.

$ sudo sh -c 'echo "deb trusty main" >> /etc/apt/sources.list'
$ sudo sh -c 'echo "deb-src trusty main" >> /etc/apt/sources.list'
$ sudo apt-key adv --keyserver --recv-keys EEA14886
$ sudo apt-get update && sudo apt-get upgrade
$ sudo apt-get install oracle-java8-installer
$ sudo apt-get install oracle-java8-set-default

Maven would now install as 3.0.5, which is to old for some packages as they need 3.3+. Latest as of this writing is 3.5.0[1][2]

$ sudo apt-get purge -y maven
$ wget
$ tar -zxf apache-maven-3.5.0-bin.tar.gz
$ sudo mv apache-maven-3.5.0 /usr/local
$ ln -s /usr/local/apache-maven-3.5.0/bin/mvn /usr/bin/mvn
$ echo "export M2_HOME=/usr/local/apache-maven-3.5.0" >> ~/.profile

Check versions, they should all report 1.8 -ish and 3.5 -ish

$ javac -version
$ java -version
$ mvn -version

Additional tweaks for maven is to set the environment variable MAVEN_OPTS in ~/.profile[3]

export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=256m"

It could also be necessary to add maven to the PATH

export PATH=/opt/apache-maven-3.5.0/bin:$PATH

Clone LanguageToolEdit

Create the dir for the LanguageTool and clone the repo[4] (Please avoid hammering the public API.[5])

$ mkdir /vagrant/languagetool
$ cd /vagrant/languagetool

For the official repo use

$ git clone --depth 5 .

For the forked repo use

$ git clone --depth 5 .

Now do a first test run (before this you should probably set more memory for the guest, like 3072MB)

$ mvn clean test package

Add the classpath to ~/.profile (could also be the common /etc/profile)

export CLASSPATH="$CLASSPATH:/vagrant/languagetool/languagetool-standalone/target/LanguageTool-3.9-SNAPSHOT/LanguageTool-3.9-SNAPSHOT/*"

Now source the ~/.profile (could also be the common /etc/profile) and start the server[6]

$ source ~/.profile
$ java org.languagetool.server.HTTPServer --port 8081

The server can now be tested by a call

$ curl --data "language=en-US&text=a simple test" http://localhost:8081/v2/check
