Resolve error obtaining dependencies: Failed to read artifact descriptor for - org.apache.http.client.HttpResponseException: Permanent Redirect (308)

I'm trying to run a legacy system (using Grails 2.3.7 and JDK 7) for development locally which until now has worked as usual.

I was getting another error that I solved deleting the folders .m2 and .grails in my home. After that, it seems maven isn't able to download the dependencies:

Error |
Resolve error obtaining dependencies: Failed to read artifact descriptor for org.grails.plugins:tomcat:zip:7.0.52.1
Error |
Resolve error obtaining dependencies: Failed to read artifact descriptor for org.grails.plugins:scaffolding:zip:2.0.2

Caused by: org.apache.http.client.HttpResponseException: Permanent Redirect (308)

Full log here.

Probably I'm missing something but the plugin can be reached from repo.grails.org repository.

How do I get around this problem?.

For the time being, I partially solved the error by copying my coworkers .m2 and .grails folder but when I change some dependency in the BuildConfid.groovy this error shows up again.

BuildConfig.groovy (repositories):

repositories {
    inherits true // Whether to inherit repository definitions from plugins

    grailsPlugins()
    grailsHome()
    mavenLocal()
    grailsCentral()
    // mavenCentral()
    // mavenRepo "http://repository.codehaus.org"
    mavenRepo "http://download.java.net/maven/2/"
    // mavenRepo "http://repository.jboss.com/maven2/"
    mavenRepo "http://download.java.net/maven/2/"
    mavenRepo "http://mavensync.zkoss.org/maven2"
    mavenRepo "http://insecure.repo1.maven.org/maven2/"
}
Solution

  • Workaround

    Besides the obvious solution of upgrading Grails, to simply solve this problem it's possible to use Java 8 to download the dependencies and Java 7 to run the application.

    1. Replace all Grails and Maven Central http repositories with its https equivalents (including grailsCentral() and grailsPlugins()):

    repositories {
    mavenLocal()
    mavenRepo "https://repo1.maven.org/maven2/"
    mavenRepo "https://repo.grails.org/grails/core"
    mavenRepo "https://repo.grails.org/grails/plugins"
    mavenRepo "https://jaspersoft.jfrog.io/artifactory/third-party-ce-artifacts"

    Don't forget to also remove the line with inherits true.

    2. Refresh (download) the dependencies using Java 8:

    If you want to do this only on Intellij, you can change SDK version at File > Project Structure > Project > SDK. Beware that Intellij may build Grails automatically so it might be necessary to restart the IDE.

    The following are the commands to refresh the project's dependencies using Grails command refresh-dependencies directly through Java in Linux or Windows.

    Linux:

    
# Change java command to Java 8 full path if needed
G_HOME="</path/to/grails_home>" java -Dgrails.home="$G_HOME"  \
    -Dgroovy.starter.conf="$G_HOME/conf/groovy-starter.conf" \
    -classpath "$G_HOME/lib/org.codehaus.groovy/groovy-all/jars/groovy-all-2.1.9.jar:$G_HOME/dist/grails-bootstrap-2.3.4.jar" \
    org.codehaus.groovy.grails.cli.support.GrailsStarter \
    --main org.codehaus.groovy.grails.cli.GrailsScriptRunner \
    --conf "$G_HOME/conf/groovy-starter.conf" \
    "refresh-dependencies"

    Windows CMD (Not tested):

    set G_HOME=</path/to/grails_home>

# Change java command to Java 8 executable full path if needed:    
java -Dgrails.home=%G_HOME% ^
    -Dgroovy.starter.conf=%G_HOME%/conf/groovy-starter.conf ^
    -classpath %G_HOME%/lib/org.codehaus.groovy/groovy-all/jars/groovy-all-2.1.9.jar:%G_HOME%/dist/grails-bootstrap-2.3.4.jar ^
    org.codehaus.groovy.grails.cli.support.GrailsStarter ^
    --main org.codehaus.groovy.grails.cli.GrailsScriptRunner ^
    --conf %G_HOME%/conf/groovy-starter.conf ^
    refresh-dependencies

    3. After downloading the dependencies (step 2), run using Java 7

    Don't forget to clean the project (delete the target folder) and change Java version back to 7.

    The problem is http://repo.grails.org is redirecting to https and no longer accepting http connections.

    I tried using Java 7 and Maven with Grails https repository enabling TLS version 1.2 support and adding Java Cryptography Extension (JCE). Eventually got stuck in a TLS handshake problem which I was short in time to solve.
