The brew one doesn't work properly most the time

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...
