Trying to build robocode tank royale (gradle errors)

[dEgolf]

Hi again!
I'm trying to build robocode tank royal using gradle. (My motivation for doing this is that I'd like to understand better exactly what API commands are doing at a low level, so I can better control my robot). However, the build fails for me with this information:

* What went wrong:
Cannot get non-null property 'robocodeDevOssrhUsername' on project ':bot-api:java' as it does not exist

I'm using Windows 10, and the following versions of some relevant software:

$ java --version
openjdk 11.0.14.1 2022-02-08
OpenJDK Runtime Environment Temurin-11.0.14.1+1 (build 11.0.14.1+1)
OpenJDK 64-Bit Server VM Temurin-11.0.14.1+1 (build 11.0.14.1+1, mixed mode)

$ dotnet --version
6.0.201

$ gradle -v

Any suggestions are appreciated.

Edit:
My current guess is that a file is supposed to be created and then saved on OSSRH, which requires credentials. If this is the problem, might it be possible to configure the build to save the file locally instead of on OSSRH?

Edit 2:
I tried commenting out things that seemed to be causing errors. I then ended up with this error:

* What went wrong:
Could not determine the dependencies of task ':server:shadowJar'.
> Could not resolve all dependencies for configuration ':server:runtimeClasspath'.
   > Could not find dev.robocode.tankroyale:robocode-tankroyale-schema:0.10.0.
     Searched in the following locations:

         project :server

I notice that the URL listed in the error message doesn't exist, although this related one does: "https://repo.maven.apache.org/maven2/dev/robocode/tankroyale/robocode-tankroyale-bot-api/0.10.0/robocode-tankroyale-bot-api-0.10.0.pom". Maybe it's looking in the wrong spot?

You are right that it was used for the Sonarype OSSRH. I have commented this out for now, so you can get a new version by doing a git pull from the master branch.

The error you see with the robocode-tankroyale-schema is because you are missing this artifact in your local maven repository.

I might have a look into making this a bit smarter. But then again. The schemas are not changed that often.

Steps:

• Go to the /schema/java
• Do a gradle build
• Do a gradle publishToMavenLocal to publish the artifact your your local repository

Now you should be able to build the Bot API for Java. :)

[flemming-n-larsen]

Sorry, the last line needs to be:

gradle publishToMavenLocal

[dEgolf]

Great! I think I got it building.
Here's what I did:

• As far as I could tell, the Sonarype OSSRH stuff wasn't commented out, even after doing a git pull.
• So, I commented out both occurrences of this block of code in bot-api\java\build.gradle.kts:

credentials {
    username = robocodeDevOssrhUsername
    password = robocodeDevOssrhPassword
}

• I also ended up commenting out this code in gui-app\build.gradle.kts and schema\java\build.gradle.kts:

signing {
    sign(publishing.publications["mavenJava"])
}

• I commented out apply(from = "../../groovy.gradle") and the whole section under register("upload") in sample-bots\csharp\build.gradle.kts and in sample-bots\java\build.gradle.kts.

• I also commented out include("buildDocs") in settings.gradle.kts.

• I was then able to successfully run gradle build and gradle publishToMavenLocal in /schema/java.

I was confused as to where the resulting files were placed once the build succeeded, but it turns out they were saved in the Maven local repository at C:\Users\David\.m2\repository\dev\robocode\tankroyale.

[flemming-n-larsen]

I have updated the build file. For some reason. the push did not succeed, and I have an issue updating my previous comments due to some temporary GitHub issue. But it is okay now.

I see that I do need to update the README with information on where to find the artifact on the local repository. 👍

Hello

I've just cloned the repo and launched a gradle build
I think the problem is still here. Looks very similar if not the same to me. I've tried all he above approaches without success and at the end I've undone everything and came back to the master HEAD, so the following error is from a clean cloned repo.

here the build error output:

~/R/tank-royale (master) [1]> gradle build

FAILURE: Build failed with an exception.

* Where:
Build file '~/Robocode-tank-royale/tank-royale/bot-api/java/build.gradle.kts'

* What went wrong:
Cannot get non-null property 'ossrhUsername' on project ':bot-api:java' as it does not exist

my system:

> gradle --version

Thank you @SirStone for following up on this issue.

I made a fix so the ossrhUsername and ossrhPassword are now optional when these are missing in the [user home]/.gradle/gradle.properties file as these are only required when publishing the Bot API artifact to the Maven Central.

I have pushed the fix to the master branch.

[SirStone]

Thank you to follow up our issues so quickly. This project is probably taking a lot of your free time, I see passion here.
Back to the problem...I still see issues in building up from a clean and updated repo

The previous problem is gone, as you said, you fixed it. So the first gradle build try failed because was trying in building .Net stuff and I don't have it rugged up right now, so I commented these lines in settings.gradle.kts

• line 5 -> // include("schema:dotnet")
• line 18 -> // include("bot-api:dotnet")
• line 22 -> // include("sample-bots:csharp")
  In order to exclude all the .Net products from the build process

Cleaning is all green, but I receive this error in building the project

~/R/tank-royale (master) [1]> gradle clean

Am I missing some steps? I followed the https://repo.maven.apache.org/maven2/dev/robocode/tankroyale/robocode-tankroyale-schema/0.13.1/robocode-tankroyale-schema-0.13.1.pom that the code is searching and I can't see it online, actually I can't open at all the https://repo.maven.apache.org/maven2/dev/robocode/tankroyale/robocode-tankroyale-schema; going back one slug in the url I can open https://repo.maven.apache.org/maven2/dev/robocode/tankroyale that shows a single folder for robocode-tankroyale-bot-api . This means that there are missing artifacts on Maven Central, at least, while I was trying this morning.

Thanks again for your efforts. With baby steps maybe one day I will start fixing things for you (an this community) instead of viceversa

Cheers

I realised that we did not need to create an artifact for the schema/java as the shadowJar task just uses the classes from the artifact.

I have updated the master branch where there is no need to build a schema/jar artifact anymore. 🙂

Hello
Thanks to holidays in Italy I had time to try again today. I've fixed my dotnet for sdk setup too and now, with no single modification to the code cloned (pulled) from the repo I'm able to do a full 'gradle build' with no errors

BUILD SUCCESSFUL in 3m 5s
43 actionable tasks: 40 executed, 3 up-to-date

Thanks for your effort, now maybe I can put some efforts of mine in this modifying the components for me or for the community

[flemming-n-larsen]

I am happy to learn that it is finally building as it should. I trying this out on Linux/Ubuntu and macOS from scratch to make sure it should work and fixed as many issues as possible.

Note:
When it comes to developing on the Bot APIs, one change to e.g. the Java version, will also need to be made for the .Net version and vice versa, so they stay in sync. At a later point, more APIs should be added. For example a web based API, and then there will be at least 3 API's that needs to be in sync at that time.
