Programmatically creating a repo via the script API

[womanderful]

Hi!

We're trying to create an APT repo via curl (ultimately from jenkins). In https://github.com/sonatype/nexus-public/blob/master/plugins/nexus-script-plugin/src/main/java/org/sonatype/nexus/script/plugin/RepositoryApi.java we can see a number of built-in methods for creating different types of repos. Does the APT plugin add a new method for this? We tried the following:

# create script
curl -u user:pass -X POST -H "Content-Type: application/json" --data '{"name":"foo","type":"groovy","content":"repository.createAptHosted('\''test'\'','\''myblob'\'')"}' http://myhost:8081/service/rest/v1/script
# run it
curl -u user:pass -X POST -H 'Content-Type: text/plain' -H 'Accept: application/json' 'http://myhost:8081/service/rest/v1/script/foo/run'
{
  "name" : "foo",
  "result" : "javax.script.ScriptException: groovy.lang.MissingMethodException: No signature of method: org.sonatype.nexus.script.plugin.internal.provisioning.RepositoryApiImpl.createAptHosted() is applicable for argument types: (java.lang.String, java.lang.String) values: [test, deb_packages]\nPossible solutions: createNpmHosted(java.lang.String, java.lang.String), createHosted(java.lang.String, java.lang.String), createNpmHosted(java.lang.String), createNpmHosted(java.lang.String, java.lang.String, boolean), createRawHosted(java.lang.String, java.lang.String), createYumHosted(java.lang.String, java.lang.String)"
}

The error suggests some alternatives but "createAptHosted" is not among them, which makes me think that this is a dead end. Or are we missing something?

We're using Nexus Repository Manager OSS 3.11.0-01 and nexus-repository-apt 1.0.7.

Thank you,

Can we put something in the json that does something similar to the groovy script "internal/provisioning/RepositoryApiImpl.groovy"? So emulate a "createAptHosted" in the json we upload using "RepositoryApiImpl.groovy" as a reference.

The "content" section of the json is in groovy. "RepositoryApiImpl.groovy" seems to provide the groovy implementations of the create functions for the other repo types.

I think these convenience methods are only for built-in repository types, so I wouldn't expect there to be a createAptHosted method. Think you'd have to implement the logic yourself in your script.

For others that are attempting this here's what worked for me:

Grab provision.sh and addUpdateScript.groovy from the below repository:

https://github.com/sonatype/nexus-book-examples/tree/book-examples-3.2/scripting/complex-script

( note I had to add @Grab('org.codehaus.groovy:groovy-backports-compat23:2.4.5') ) to addUpdateScript.groovy

@Alan01252 ,
OK, I understand all the code above, but what to do then. Is there a way to only run script, but not add and then run? because adding script and then running causes another issue, we must remove that script after running, otherwise we will get duplication exception from nexus API. So please anybody help me on finding a better way of only running, but not adding then running the specified script.

[Alan01252]

HI, @hmkhitaryan Did you have any luck? I'm not entirely sure I understand what you're asking but happy to help if I can.

[hmkhitaryan]

Dear @Alan01252 , the thing is so, I can create, delete repositories programatically, but every time I send "http://localhost:8081/service/rest/v1/script/{name}" request, I have to send this request then
"http://localhost:8081/service/rest/v1/script/{name}/run" for running the script, and then to send DELETE "http://localhost:8081/service/rest/v1/script/{name}" to avoid duplication exception. now I want to implement such logic for only to run script, but not add and then run. I have heard that it exists such solution.
