Set Up I2P on Mac OS X

I2P OS X.md

• Install I2P
  • Download I2P
  • java -jar i2pinstall_*.jar
• Install Java Service Wrapper
  • Download Community Version
  • tar xzf wrapper-*.tar.gz
  • cp wrapper*/bin/wrapper /Applications/i2p/i2psvc
  • cp wrapper*/lib/wrapper.jar /Applications/i2p/lib
  • cp wrapper*/lib/libwrapper.so /Applications/i2p/lib
• Try to start I2P using /Applications/i2p/i2prouter start or Start I2P Router app
  • tail -f /tmp/wrapper.log and look for any problems
• Configure FireFox browser
  • Install FoxyProxy
  • Set HTTP Proxy: 127.0.0.1, Port: 4444
  • Whitelist https?://127.0.0.1/*
  • Whitelist *.i2p/*
• Install I2PMonitor
  • Download I2PMonitor
  • Install I2PControl Router Plugin
    • Open router console in the browser and navigate to clients settings.
    • Enter following URL into the “Plugin Installation” field: http://plugins.i2p/files/I2PControl.xpi2p and click on “Install Plugin”.
  • Wait until plugin is downloaded and installed. Be patient, it can take time, if your router is not yet good integrated into network.
  • Launch I2PMonitor app

As a complete alternative, you can just do brew install i2p.

I did this on MacBook Air (M2-ARM chip) and when I do i2prouter start its shows:

Waiting for I2P Service..................
WARNING: I2P Service may have failed to start.
**Failed to load the wrapper**

The most likely reason is that a supported version of the java
wrapper is not available in the I2P installation package for your
platform. It may be possible to manually download and install
a compatible wrapper for your system.
See https://geti2p.net/en/misc/manual-wrapper for hints.

In the meantime, you may start I2P by running the script
/opt/homebrew/Cellar/i2p/2.0.0/libexec/runplain.sh

Running /opt/homebrew/Cellar/i2p/2.0.0/libexec/runplain.sh gives me

I2P started [5268]
/opt/homebrew/Cellar/i2p/2.0.0/libexec/runplain.sh: line 54: %SYSTEM_java_io_tmpdir/router.pid: No such file or directory

However I can access http://127.0.0.1:7657/home

Why is the Homebrew formula missing the entry in /Applications ?

Why doesn't the Homebrew formula register a compatible edition of the JVM for the i2p package?

Why go to the bother of the JVM only to be defeated by ISA's...
