Using Geotools from Clojure - Unhandled java.lang.NoSuchFieldError METER

Question

Okay, so the guts of the issue is I'm getting this error:

 Unhandled java.lang.NoSuchFieldError
 METER

When calling a function that uses some geotools functionality from org.geotools/gt-shapefile. My starting version was 15.1.

The weird thing is that we're using this project (version 13.2) in a virtually identical app, using the same calling code and same namespace to call from; yet using that version doesn't work here - the same error is thrown.

I've tried:

multiple versions of the lib in question, starting with 15.1 and rolling back from there
multiple versions of clojure
multiple versions of our internal libs that differ between the two projects

I've seen from looking around that this seems to be a dependency issue, but I'm not sure exactly where it occurs.

Calling code is the same, so didn't seem relevant. It's a fresh lein app from a template, so the only differences are in deps. — Alex Lynham, Oct 12 '16 at 14:26

After quite a while, I managed to work this out - and wanted to make sure it was on SO for posterity. The problem is in the javax.measure library; you can see the fields here. There are two versions on maven and continued development post-May 2010 is elsewhere.

A lot of projects mix this in, and dependency mismatch can happen pretty easily. In our case, Apache Tika was the culprit. One of our internal libs uses Tika, and that uses:

[javax.measure/jsr-275 "0.9.3"]

Whereas Geotools uses:

[net.java.dev.jsr-275/jsr-275 "1.0-beta-2”]

Thus, adding the following to any projects in your project.clj that refer to javax.measure will solve the issue:

 [library "x.x.x" :exclusions [javax.measure/jsr-275]]

To identify these, use $ lein deps :tree to explore your dependencies.
