Randomly Hangs Forever

[jeb2239]

./gradlew go:build
Starting a Gradle Daemon (subsequent builds will be faster)

Found go 1.8.3 in /home/username/go/bin/go, use it.
<=============> 100% CONFIGURING [3s]
IDLE
<=============> 100% CONFIGURING [1m 9s]

It also make no progress. Has this happened to anyone?

[blindpirate]

Nope, it's the first time I see this problem. Some questions:

• Gradle version?
• Gogradle version?
• OS environment?
• Is it a multi-project?
• Since it hangs in configuration phase, do you have any other logic in build.gradle
• How frequent does it hang?

My advice:

• Remove all logic except apply plugin logic in build.gradle
• turn on --debug and show me the log
• If you can provide a minimum reproducible example, I would appreciate it.

[jeb2239]

gradle is 4.1

gogradle is 0.7 most recent

OS is redhat linux 6.8

yes there is a scala project and go project

go
│   ├── bin
│   │   └── govendor
│   ├── build.gradle
│   └── src

| ----common

[jeb2239]

Also what is this packagePath. I don't understand what its purpose is

plugins {
    id 'com.github.blindpirate.gogradle' version '0.7.0'
}


golang {
    packagePath = 'github/myproject' // go import path of project to be built, NOT local file system path!
}

[jeb2239]

Like what does this happen

* What went wrong:
Execution failed for task ':go:resolveBuildDependencies'.
> Exception in resolution, message is:
  Cannot recognized package: nova/common/config
  Resolution stack is:
  +- github/mypacj

[blindpirate]

Well... I highly recommend you to take a look at the doc, which tells you what is golang package.

Anyway, is the project structure that you pasted root project or just a sub project? Please see java and go mixed example as an example.

Please let me know if there's anything not clear.

[jeb2239]

does one app execuable = one project?

[blindpirate]

A go project can produce mutiple app executable, but don't mix scala code and go code in one project (i.e. apply both golang and scala plugin in one project).

[jeb2239]

yes so my top level build.gradle is actually empty and there are two top level folders one is named go and the other is named scala

[blindpirate]

ok, I guess I know what bothers you. Where does nova/common/config emerge and what's your expectation of this package?

[jeb2239]

so if I navigate into the go directory i have three folders

bin (pre-gogradle) , src (pre-gogradle) , vendor (this was generated by gogradle) , also I have build.gradle

plugins {
    id 'com.github.blindpirate.gogradle' version '0.7.0'
}


golang {
    packagePath = 'nova' // go import path of project to be built, NOT local file system path!
}
dependencies {
    golang {
        build name:'github.com/DisposaBoy/JsonConfigReader'
        build name:'github.com/denisenkom/go-mssqldb'
        build name:'github.com/gorilla/mux'
        build name:'github.com/sirupsen/logrus'
        build name: 'nova/apps/example'
        
    }
}

then i go into src directory
there is
nova/apps/example/configExample.go
nova/common/config/jsonconfig.go
nova/framework/data/data.go
nova/vendor/vendor.json <--- this was pre gogradle , we are currently using govender.

[blindpirate]

The project structure you pasted previously is such a mess...

Actually, your structure should be:

go
├── build.gradle
├── apps
├── common
└── framework

And in your build.gradle:

golang {
    packagePath = 'nova'
}

However, you really need to read https://golang.org/doc/code.html first.

[blindpirate]

And try to make it work in single project, then integrate it with your scala project.

[jeb2239]

So I read more about go and made this project https://github.com/jeb2239/practice_go . Some things I don't understand is why does there need to a separated directory for each main.go file . Also I still don't understand how this system can be used to build multiple binaries even when I explicitly have 2 go build commands it only makes one of the binaries. Thank you so much for your help!

[blindpirate]

First question, that behavior is determined by go build command. There should be one main package for each executable.

Second question, for the moment, you need to use the following build.gradle to achieve your goal:

plugins {
    id 'com.github.blindpirate.gogradle' version '0.7.0'

}

golang {
    packagePath = 'nova' // go import path of project to be built, NOT local file system path!
}

task build2(type: com.github.blindpirate.gogradle.Go){
    go 'build -o exampleTwo  nova/apps/example/exampleTwo'
}

build {
    dependsOn build2
    go 'build -o mainExample nova/apps/example/mainExample'
}

The reason is only one command is allowed in build task. So the latter overwrote the former. I should improve it in next release.

[jeb2239]

why do we need .gogradle and the symlink - this seems to be a gogradle specific requirement.
Ideal situation would be to have src/nova/apps .

[blindpirate]

The symlink is not necessary.

If you confrom to golang's standard structure and have everything under GOPATH, the symlink won't be created. But in this way, it's hard to integrate it into your scala project.

As for .gogradle, it's just a directory to store some temp files, just like .gradle, .idea.

[jeb2239]

Also why does gogradle resolve dependencies from the latest commit even when a specific commit is requested.

This problem also exists in 0.6.5 but not 0.5.4.

[blindpirate]

@jeb2239 The reason why the latest commit is resolved is that it's someone's transitive dependency. "Resolve" means fetching the metadata and resolving conflict. In this case, you specify a commit, but transitive dependencies includes another version (latest commit), so both will be "resolved" and the latest one will be discarded (See here for conflict resolution strategy). And you can use ./gradlew dependencies to see the dependency tree.

Could you take a look at the final version installed into vendor, is it the correct version (the commit you specified)?

[blindpirate]

@minid33 Does this occur every time? Would you like to try the latest 0.7.0?

I can't find any issue in the log you pasted, so it would be great if you could give me a sample to reproduce it.

[minid33]

Without failure @blindpirate, I first encountered this in latest 0.7.0 which I why I went back to see when it didn't exist.

This is a copy of our build.gradle after running gradle init and a few tweaks.

plugins {
    id 'com.github.blindpirate.gogradle' version '0.7.0'
}

golang {
    packagePath = 'company.com/company/product-name/main'
}

repositories {
    golang {
        root ~/git\.company\.com\/company\/[\w-]+/
        vcs 'git'
        url { 
            "ssh://git@company.com/company/${it.split('/')[2]}" 
        }
        
    }
    golang {
        root 'appengine'
        emptyDir()
    }
}

 dependencies {
    golang {
        some mix of many lines like 
        build name:'company.com/company/client/stuff', version:'HEAD', transitive:false
        build name:'github.com/person/project', 
        version:'<commitsha>', transitive:false
        etc
    }
}

[blindpirate]

build.gradle looks correct. Do you mind pasting the whole debug log to somewhere like gist.github.com so that I can take a look at it? Of course, you can remove the confidential information.

[minid33]

I read the whole log and I guess this is what you're looking for...

This is a golang install using brew install go and after updating from 1.8 to 1.9 it made no difference.

This is when GOPATH=/Users/minid33/golang and GOROOT=/usr/local/opt/go/libexec are set as env vars and unset

[minid33]

looks like resolveIfNecessary() or something further down the chain needs to either accept the GOEXE env var (it probably should even if this isn't the fix) or the path resolution for macs needs to be fixed, for me it's /usr/local/bin/go after installing with go, it cannot be sim linked because of mac security.

Full logs are here:

Not really. Gogradle will try to access all path in PATH to find a local go executable, and that's why this error emerges in the debug log. You can find a line in your log:

13:05:45.949 [QUIET] [com.github.blindpirate.gogradle.crossplatform.DefaultGoBinaryManager] Found go 1.8.3 in /usr/local/bin/go, use it.

So that's definitely not the problem.

However, after examining you log, it hangs in resolveTestDependencies task, which is maybe where the potential bug happens. I need your help to narrow down the location.

• First, please run gradle clean before gradle vendor and see if it still happens.
• If yes, remove the vendor directory and run gradle vendor and see if it still happens.
• If yes, try to comment all the test dependencies in you build.gradle and see if it still happens.

Thanks a lot.

clean before vendor doesn't change the outcome.

the .gogradle/ folder is empty after gradle clean, I erased it and ran again and had the same results.

There are no test dependencies in this build.gradle file. There never have been, I think this is the default behaviour of gradle init

changed a build dependency to a test dependency and also had the same results.

[blindpirate]

Thanks for the response. That's weird, do you have gogradle.lock in your project? If there's no test dependencies at all, I have no idea about why it's stuck at resolveTestDependencies.

Now could you please remove all build dependencies in build.gradle and retry? Or maybe you can remove stuff in build.gradle gradually to find which part of build.gradle caused this problem?

I really want a sample which I can run in my machine to reproduce it if possible.
