Grails fails to resolve dependency

Question

I cannot figure out why grails fails to resolve dependency.

When I ran

grails war --stacktrace --verbose

I could see in the log:

...

Server access Error: Connection timed out: connect url=https://repo.grails.org/grails/plugins/org/grails/plugins/tomcat/8.0.33/tomcat-8.0.33.pom

...

but the link could be opened and downloaded in the browser. I thought that proxy might cause it. But after I set it with:

grails add-proxy client --host=<ip> --port=<port>

the error remained.

I'm using

Grails 2.5.6

Java 1.8

Windows 10

I cannot figure out how dependency resolution mechanism works in Grails. I also tried to run Grails 3.3.9 right after the extraction of the downloaded zip-archive. I ran grails not from a Grails-project folder.

And the first I saw was:

| Error Error occurred running Grails CLI: Could not find artifact org.grails:grails-bom:pom:3.3.9 in nexus (http://<ip>:<port>/nexus/content/groups/public) (Use --stacktrace to see the full trace)

How does it know about

http://<ip>:<port>/nexus/content/groups/public

This is a setting from my Maven. How are they related?

Answer 1

After you run grails add-proxy client ... you need to tell Grails to use that proxy with grails set-proxy client .

If you want to review it, the proxy config is stored in %USERPROFILE%\\.grails\\ProxySettings.groovy

add-proxy should add the proxy definition and set-proxy should set an unique line currentProxy='client'

Grails 3 uses Gradle as the build system so I guess you configured Gradle to use a Maven repo in %USERPROFILE%\\.gradle\\settings.gradle
