When I use PathEnv for building pod with native sources (java), I encounter some problems:

As you can see, BuildScript tries to pass my $FAN_ENV_PATH as fan.home to fanx.tools.Jstub, but $FAN_ENV_PATH is not a full-blown fantom installation, it’s a folder where some additional libs (local env) are stored. That’s why it cannot find sys.pod here.

So, I’ve copied fantom-1.0.58/lib/** and fantom-1.0.58/etc/** to get it run.

BUILD FAILED [6881ms]!

As you can see, it now tries to update pod file after java compilation but uses wrong location based on $FAN_HOME.

What was expected?

1. Using util::PathEnv, pods should be looked up first in $FAN_ENV_PATH, then in $FAN_HOME even when compiling java sources.
2. Output pod file should be correctly written and updated at first $FAN_ENV_PATH path (as specified in Fantom docs).

Does it make any sense or am I doing something wrong here?

BTW, you can add

div.fandoc pre { white-space: pre-wrap; }

to fix long code lines overflow.

Thanks @tonksy - they will actually get an overflow:auto when this site gets the new version of sidewalk (so we don't get unintentional line-breaks).

Promoted to ticket #1534 and assigned to brian

I will take a look.

If you have patch you want to email me, that would be great.

That works for me (I’ve even tried it with two different paths in PathEnv simultaneously):
