Maven Error

[willemneal]

Hey Jon,

I've been playing around with Phosphor for sometime now and I think it's awesome. I'm trying to add instrumentation to add either a method or a field for each loop in a class and "taint" it with the loop condition. That is to say set that field with the variable of the loop condition or pass it to a void function. This way I can add the loops to the list of sinks.

That being said I'm very new to ASM and low level bytecode stuff and I found this when looking around for resources. Phosphor itself was pretty advanced usage of ASM and this project looked like the perfect introduction. Thanks for putting it together!

When I try to run "mvn package", however, I get the following error and I haven't found anything online that helps (I'm also new to maven).

tia,
WIllem

Oops.. It looks like this was half-finished example :/

I just committed the rest of it. Now you can do mvn package. You can then do java -jar target/instrumenter-maven-plugin-0.0.1-SNAPSHOT.jar and run it on any code. Or, you can use it as a maven plugin. In that case, do mvn install, and then for an example, look at staticInstrumenterUsage, where (after doing a mvn install in the instrumenter plugin) you can do mvn package, and then note the generated files in target/classes-instrumented and target/test-classes-instrumented.

Let me know if you'd like to chat at all about Phosphor... I am now a Professor at GMU, and live in DC ~10 miles from UMD and would be happy to come out for a visit.
