Getting an error about simpletool HOT 7 CLOSED

Hey @RoySRose,
Thanks for taking the time to look into GraalVM instrumentation!
Yeah, the documentation for instrumentation is currently a work in progress (as is this repo which is meant to be a starting point for development), hopefully we will have some better guides soon :)

So, I just double checked that the setup here works for me. What I did was point JAVA_HOME to GRAALVM_HOME and run
mvn clean package && ./runJsWithCoverage.sh
Seems like you are on a mac and I am running linux so maybe (though not likely) there is a subtle difference of some kind...

Maybe we can do a few sanity checks:

• Is the simpletool-19.2.0.jar in the target folder?
• could you provide the output of ./simpletool js --version:graalvm
• check that ./simpletool js --help:tools contains a Simple Code Coverage entry

Hello, Thank you for your time taking look at this. As you've commented I also don't think it's the mac that causes this. Well, it's what Graalvm is for, 'running multiple languages on one vm'. (of course, there is also native part)
I've followed your instructions and checked as below

1. I've changed $JAVA_HOME to $GRAALVM_HOME in simpletool script
   

2. my $GRAALVM_HOME points to graalvm-ce-19.2.1
   

3. Yes there is simpletool-19.2.0.jar in the target folder?
   
   (just added few print in example.js)

4. I can't run ./simpletool js --version:graalvm with below error.
   

But I can run it if I remove --simple-code-coverage \ from simpletool script, and the result is as below

5. I'm trying to check ./simpletool js --help:tools contains a Simple Code Coverage entry, I've run the command but I'm afraid I don't know how to check the entry. posting the results below. If you can guide me more on this. I will check right away.

Please let me know if there is anything for me to check additionally.

Unusual... Seems that the tool is not picked up when being appended to the classpath.
Would you please run the following to make sure it's not a path issue.
$GRAALVM_HOME/bin/js --jvm --vm.Dtruffle.class.path.append=/absolute/path/to/simpletool-19.2.0.jar --simple-code-coverage -e '1+1'
for me the output is as follows:

==
Coverage of null is 100.00%
+ 1+1

from simpletool.

Unfortunately... no luck

seems --simple-code-coverage option(?)/tool(?) is still not recognized.

So far I know, Graalvm CE 19.2 is the latest version. Do you think I should try with another version?

Have tried with graalvm-ce-19.1.1, still no luck..

any suggestions? that I can try?

As a sanity check I re-ran the gate with 19.2.0 (https://travis-ci.org/boris-spas/simpletool/jobs/614411116?utm_medium=notification&utm_source=github_status) and with 19.2.1 (https://travis-ci.org/boris-spas/simpletool/jobs/614414957?utm_medium=notification&utm_source=github_status) and both pass.

I'm running low on ideas about whats special about your machine :/

@boris-spas

First of all, Once again thank you for your time.
I looked at your travis link.
Decided to start from scratch.

Fortunately, It worked.

Got back and searched for the reason.
I found out the option was not being registered.

@Option(name = "", help = "Enable Simple Coverage (default: fa......

Something wrong about auto generated SimpleCoverageInstrumentOptionDescriptors.class

But it was due to some kind of dependency error. I couldn't dig it deeper. But it was solved after re-updating the dependencies.

Anyway. Thank you again.
I'll start looking into truffle instrument api, hope to reach you with good new.

Good stuff! I'll close the issue then!
