Error compiling Perspective SDK example with Gradle

I cloned the IA Git Hub repository and tried to compile it per instructions…it fails. Below is the output of my Git Bash command line when I execute gradlew.bat buildModule, it times out trying to load and cache rxjs-6.5.2.tgz.

What’s strange is that when I type https://registry.yarnpkg.com/rxjs/-/rxjs-6.5.2.tgz into a new browser page the zipped tar file downloads in a couple of seconds. Assuming it is a legitimate timeout I went to ...ignition-sdk-examples\perspective-component\web\.gradle\yarn\yarn-v1.22.4\node_modules\yarn\lib\cli.js and changed the time from 30* to 1000* var NETWORK_TIMEOUT = exports.NETWORK_TIMEOUT = 10000 * 1000; // in milliseconds only to find out after trying to build the module that the cli.js file is being over written by (I don’t know what, but a new download from a respository?) and the timeout goes back to 30*.

I’m a little flummoxed, any guidance is appriceated.
Thank you and regards,
Ted.

What java version are you running?

D:\>java -version
openjdk version "1.8.0_282"
OpenJDK Runtime Environment (Zulu 8.52.0.24-SA-win64) (build 1.8.0_282-b08)
OpenJDK 64-Bit Server VM (Zulu 8.52.0.24-SA-win64) (build 25.282-b08, mixed mode)

I also tried to execute javac -version but it said it didn’t recognize the command. I’m not sure I understand this…it doesn’t look the same as I remember it when I set it up after installing Ignition. In my environment variables JAVA_HOME is set to C:\Program Files\Java\jdk-11.0.11 and Path is set to C:\Program Files\Zulu\zulu-8-jre\bin\. I added C:\Program Files\Java\jdk-11.0.11\bin to my Path variable and moved it up, above the Zulu bin path. Last week corporate IT pushed a software update, I’m sure they changed my environment variables…again. Now I get this from my command prompt (after a reboot):

C:\>java -version
java version "11.0.11" 2021-04-20 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.11+9-LTS-194)

C:\>javac -version
javac 11.0.11

I tried the build again using gradlew.bat buildModule, pretty much got the same result:

I tried executing gradlew.bat buildModule --stacktrace but it just returned the command prompt. Rebooted, tried again, same thing. I definitely don’t get that. I will keep trying.

WTH???

Fixed the gradle batch file issue (copied the source from git hub). Ran again with --stacktrace option, heere are some snippets:

Ugh…it gets deeper all the time. Ran the build again this time using --scan for more insight. Some of the results are:

Are you using wifi or have a poor internet connection?

try adding this in .yarnrc file in your project root:

network-timeout 600000

maybe disable firewall

Yes, the connection is poor, home WiFi via DSL connection over a 30+ year old classic 4 telephone cable…and going through the corporate network on some kind of VPN. I will try what you suggest, thank you Victor. I’ll also disable the corp VPN and go direct. Weird though, I can go directly to the registry in a new browser instance and the tgz downloads in a second or two.

Ugh, now it fails on this…before it gets calls :web:yarn

.

IT FINALLY WORKED!!!
It has failed multiple times. I closed IA example repository again, but this time to a folder outside of my local git repository and after 3 tries, with your timeout suggestion, and off the corporate VPN it finally worked. Maybe one day they’ll install fiber in my neighborhood.

Thank you Victor!

Oof. Now just make sure to never .gradlew clean, I guess…

It might be possible to manually put a download file in the right location next time; I’m not sure what level of caching yarn/npm do for this stuff.

Follow up and FYI…
Just to test, I re-established my corporate VPN for all internet access and tried the build again from the project folder inside my git repo. It failed multiple times. Sometimes it said it couldn’t delete the .cmd files (different one each time) and sometimes it timed out trying to access the yarnpkg.com registry. The .cmd files are

D:\code\GitRepo\ignition-sdk-examples\perspective-component\web\.gradle\npm\npm-v6.4.1\npn.cmd

and

D:\code\GitRepo\ignition-sdk-examples\perspective-component\web\.gradle\npm\npm-v6.4.1\npx.cmd

I changed the network timeout from network-timeout 600000 to network-timeout 2400000

It worked, but it took a long time

> Task :buildModule
Unsigned module has been created at D:\OneDrive - Siemens Energy\GitRepo\ignition-sdk-examples\perspective-component\build/
BUILD SUCCESSFUL in 10m 17s

Maybe I can now, after increasing the timeout, but I hesitate :slight_smile:

more than 10 minutes? 600000 was 10 minutes it really failed for just 17 s xd
But yeah i suggest not to clean unless you are sure its needed or going on a break while its bussy.
Increasing network timeout is just a bandaid, and no solution to poor internet/chance on package loss.
Id also suggest working from ethernetcable instead of wifi.
If that is no option, maybe try a powerline adaptor ^^

It’s good to have options (powerline adaptor), thank you Victor.
