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

• 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 https://www.gnu.org/software/gettext/
• Build environment must use a UTF-8 locale.

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.

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

Automatic CI builds are available at the continuous integration page.

For more information how to run I2P in Docker, see Docker.md
