Building packages from source

To get development branch from source control: https://geti2p.net/newdevelopers⁠

Prerequisites

• Java SDK (preferably Oracle or OpenJDK) 8 or higher
  • Non-linux operating systems and JVMs: See https://trac.i2p2.de/wiki/java⁠
  • Certain subsystems for embedded (core, router, mstreaming, streaming, i2ptunnel) require only Java 6
• Apache Ant 1.9.8 or higher
• The xgettext, msgfmt, and msgmerge tools installed from the GNU gettext package http://www.gnu.org/software/gettext/⁠
• Build environment must use a UTF-8 locale.

Ant build process

On x86 systems do:

ant pkg

On non-x86, use one of the following instead:

ant installer-linux
ant installer-freebsd
ant installer-osx

Run 'ant' with no arguments to see other build options.

Gradle build process

Full builds of installers or updates are not yet possible, but the code can be compiled with:

./gradlew assemble

This will download dependencies over the clearnet by default, including Gradle itself. To download through a SOCKS proxy (e.g. Tor), add the following lines to your ~/.gradle/gradle.properties:

systemProp.socksProxyHost=localhost
systemProp.socksProxyPort=9150

Development builds

Automatic CI builds are available at the continuous integration⁠ page.
