Change to gradle version for newest JDK?

[jamesgolden1]

[This is unnecessary if we are moving away from the RDT - I know Brian has mentioned this, and I saw a few isetbio commits, but I'm not sure of the status on that.]

After upgrading to MacOS High Sierra Version 10.13, I had to reinstall the JDK. I perhaps unwisely chose the latest version, and this led to problems with the RDT, specifically when running the following from Matlab [as a test for the RDT]:

rdt = RdtClient('isetbio');
rdt.crp('/resources/data/istim');
data = rdt.readArtifact('barMovie_osLinear', 'type', 'mat');

I received the following error:

Error using gradleFetchArtifact (line 121)
error status 1 (
FAILURE: Build failed with an exception.

* What went wrong:
Could not determine java version from '9.0.1'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get
more log output.
)

Error in rdtReadArtifact (line 91)
    [localPath, pomPath, downloads] = gradleFetchArtifact(configuration.repositoryUrl, ...

Error in RdtClient/readArtifact (line 287)
                [data, artifact, downloads] = rdtReadArtifact(obj.configuration, ...

I tried reinstalling earlier versions of the JDK, but that didn't work for a number of reasons (apparently the install would check if OSX was newer than 10.7, and 10.13 is less than 10.7, even though it should be 10.13 versus 10.07; anyway...). Some advice from this post led to changing RDT/extenral/gradle/gradle/wrapper/gradle-wrapper.properties to run a newer version of gradle that is compatible with the latest JDK:

#Fri Sep 11 10:12:51 EDT 2015
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
#distributionUrl=https\://services.gradle.org/distributions/gradle-2.6-bin.zip
distributionUrl=https\://services.gradle.org/distributions/gradle-4.3-bin.zip

This fixed things enough so that the above commands for getting data from the RDT works, but I haven't tried much else, so this could end up causing other problems.

We seem to have to upgrade to Gradle 4.4 when we update to Java 8/9. We need to post instructions about this from Zhenyi, who made it work. Also @DavidBrainard made it work for him.

In my case, however, I couldn't move forward. I am not sure about the whole Java, JDK versions on my computer. I need a model of the situation. How do I check which versions I have?

So, to keep working and be able to ieValidateXXX

• @DavidBrainard had me clear ~/.gradle
• Then, I did a git checkout 5af0043
• to the earlier gradle version.
• I saved this as the branch 'beforegradleupdate'.

Everything runs for me. Now, I need to figure out how to upgrade to the modern versions.

Thanks for the help on this! I had a problem uploading with the RDT that came about because I am still running Matlab 2015. Just in case anyone gets the 'Response stream is undefined' error, look at line 84 of rdtRequestWeb.m:

if forceFallback || verLessThan('matlab', '8.6')
    %% Fall back on third-party RESTful utility.
    ...
else
    %% Use official RESTful utility
    ...
end

This conditional should be false for anyone with a recent version of Matlab where the 'webread' and 'webwrite' commands are included. I had to change the '8.6' because my version is '8.5', and then uploading worked. This is my fault, and I know this fix is ugly, but I wanted to record it in case anyone has the same problem.
