org.yaml:snakeyaml dependency is giving an error because 'android' classifier

[yolave]

In the pom.xml file, the declared dependency for org.yaml:snakeyaml has the 'android' classifier so, when a project compiles, it gets an error because the name of the library who is tried to be downloaded (from jcenter: https://jcenter.bintray.com/org/yaml/snakeyaml/1.17/snakeyaml-1.17-android.jar, from maven central: https://repo1.maven.org/maven2/org/yaml/snakeyaml/1.17/snakeyaml-1.17-android.jar). My project is a normal java one (not android) and i'm using Gradle instead Maven.

• is it possible to remove this classifier if it is not really used?
• if the request above can't be done, do you know any method to fix this?

Thank you!

Same issue here :-/

I have also encountered this issue. please fix. I am using this library in a spring boot project

For all those reporting the same issue, i did configure my project to avoid this problem. Simply, go to your build.gradle file, exclude the problematic dependency and then add it again:

implementation ('com.github.javafaker:javafaker:0.14') { exclude module: 'org.yaml' } implementation group: 'org.yaml', name: 'snakeyaml', version: '1.17'

[codingricky]

Which version of java-faker are you using? The latest version uses snake-yaml 1.20 which is resolvable.

[yolave]

In my case, i'm using the version 0.14. The POM file for this release has the snake-yaml 1.19 with the classifier "android", so Gradle or Maven can't find the library in any remote repository.

Here's an extract from the POM file for the release version 0.14 of Java-Faker:

<dependency> <groupId>org.yaml</groupId> <artifactId>snakeyaml</artifactId> <version>1.19</version> <classifier>android</classifier> </dependency>

This works..

[codingricky]

@yolave could you use the latest version 0.16 and see if you've get the same error?

Thanks

[yolave]

OK @codingricky , i've performed some tests over my project changing the library version. What i've found is there are two problems with the mentioned library above.

The first problem is with the org.yaml:snakeyaml:1.17 library. This library is used in other projects like Spring Boot (1.5.9-RELEASE) and Google Cloud Appengine Plugin (0.3.9) and they eventually replace the version defined by java-faker when build. When i run the gradle --dependencies command, i get this:

default - Configuration for default artifacts. +--- com.github.javafaker:javafaker:0.16 | +--- org.apache.commons:commons-lang3:3.5 -> 3.7 | +--- org.yaml:snakeyaml:1.20 -> 1.17 | \--- com.github.mifmif:generex:1.0.2 | \--- dk.brics.automaton:automaton:1.11-8 \--- project :reelder-dom \--- project :reelder-utils \--- org.apache.commons:commons-lang3:3.7

Another library is overwriting the default version of the dependency used by java-faker (1.20 -> 1.17). I've tried to force to use the defined version of the library in java-faker's pom but with no success. Suggestions will be accepted to try to fix this.

The second problem is related to the library itself. where the classifier is defined in the project's pom file. As i posted above, the pom.xml for the java-faker project has the <classifier>android</classifier> tag, so, even if the first problem described above is fixed, when a project will compile, gradle would try to use/download the library snakeyaml-1.20-android.jar, which does not exist in any remote repository.

If you need any other test, drop me a comment and I'll try to help out.

[yolave]

UPDATE

I perform a new test and i found what is going on. My project is a spring boot type one, so i have in the root build.gradle file, the option to apply the spring boot plugin (apply plugin: 'org.springframework.boot') to all the subprojects. With this, if any sub project is using a specific library version used by others libraries, they will be overwritten by the defined by the spring boot plugin. This would be fixed forcing to use the defined version in the transient libraries, however, i have not had any luck with this. By the way, the snakeyaml added the android classifier library to jcenter since the version 1.18, so any reference to a lower version will fail when try to download it. That's the reason why my project is trying to download the snakeyaml-1.17-android.jar and fails.

Same issue ! :'(

For all those reporting the same issue, i did configure my project to avoid this problem. Simply, go to your build.gradle file, exclude the problematic dependency and then add it again:

implementation ('com.github.javafaker:javafaker:0.14') { exclude module: 'org.yaml' } implementation group: 'org.yaml', name: 'snakeyaml', version: '1.17'

You should exclude library by artifact, not by group. In my case correct line is { exclude module: 'snakeyaml' }

[Samyssmile]

This solved it for me

implementation ('com.github.javafaker:javafaker:1.0.2') { exclude module: 'org.yaml' } implementation group: 'org.yaml', name: 'snakeyaml', version: '1.26'

But dirty workaround anyway.

[RockyMM]

@Samyssmile what you did should be solved with #470

[SonaliSammy]

This issue is fixed with version 0.18 of Javafaker

[vinz486]

This issue is fixed with version 0.18 of Javafaker

I'm still having this issue with javafaker 1.0.2

[SonaliSammy]

This issue is fixed with version 0.18 of Javafaker

I'm still having this issue with javafaker 1.0.2

i checked with Javafaker 1.0.2 version after your message. I don't get issue in that version even. i was facing issue with javafaker 0.14. with Upgrade my problem got resolved. Javafaker 1.0.2 they use both snakyaml 1.2.3 and snakeyaml 1.2.3-android.

[vinz486]

Hi, try to include javafaker as lib in another lib. Then try to use that lib in a project referencing it by maveLocal.

Gradle complains about missing snakeyaml android: probably the fix is not working using Gradle on maven local.

Bye.

@vinz486 , please make a sample project where your problem could be reproduced.

0.18 works Using maven

[Mahoney]

I've suddenly got this issue because a different dependency brought in org.yaml:snakeyaml:1.30 transitively, and gradle's dependency resolution combines that with java-faker's android classifier to produce a dependency on org.yaml:snakeyaml:1.30-android - which doesn't exist:

> Could not find snakeyaml-1.30-android.jar (org.yaml:snakeyaml:1.30).
  Searched in the following locations:
      https://repo.maven.apache.org/maven2/org/yaml/snakeyaml/1.30/snakeyaml-1.30-android.jar

I checked out this project and it builds fine if I remove <classifier>android</classifier> from the snakeyaml dependency.

[bodiam]

@Mahoney'm this has been fixed in Datafaker, an active clone of this repo with most of not all issues fixed.

[Mahoney]

@bodiam thanks - I'll consider migrating to datafaker. net.datafaker:datafaker, presumably?

In the meantime, this works as a way to strip the android classifier:

configurations.all {
  resolutionStrategy.eachDependency { details ->
    if (details.requested.module.toString() == 'org.yaml:snakeyaml') {
      details.artifactSelection {
        it.selectArtifact(DependencyArtifact.DEFAULT_TYPE, null, null)
      }
    }
  }
}

[debop]

@Mahoney Thanks your suggestion. it works.

this is kotlin-dsl port

    configurations.all {
        resolutionStrategy.eachDependency {
            if(requested.module.toString() == "org.yaml:snakeyaml") {
                artifactSelection {
                    selectArtifact(DependencyArtifact.DEFAULT_TYPE, null, null)
                }
            }
        }
    }

Hi there, I got the issue Could not find snakeyaml-1.30-android.jar (org.yaml:snakeyaml:1.30). Searched in the following locations: https://repo.maven.apache.org/maven2/org/yaml/snakeyaml/1.30/snakeyaml-1.30-android.jar with spring boot 2.7.1 but working well with spring boot 2.6.2

[bodiam]

@RyoSaeba06 this if a known issue. The recommendation is to use Datafaker.net, a maintained fork of this library

[pathiec92]

If you are using gradle-kotlin, use the below code to resolve this issue.

implementation("com.github.javafaker:javafaker:1.0.2"){ exclude ( "org.yaml") } implementation (group= "org.yaml", name= "snakeyaml", version= "2.0")

[phuongnq]

I'm using gradle-groovy and the following work for me:

implementation ('com.github.javafaker:javafaker:1.0.2') {
    exclude group: 'org.yaml', module: 'snakeyaml'
  }
