I'm hitting occasional Java Linkage errors when using the Grails Release plugin and am completely stumped as to how to resolve the problem. I would appreciate some suggestions. The errors vary but are in the same area.
I'm seeing the following types of error messages when trying to run publish-plugin:
09:32:36 | Generating POM file.....
09:32:36 | Error Error executing script PublishPlugin: Class org.apache.http.message.BasicNameValuePair does not implement the requested interface org.apache.http.NameValuePair (Use --stacktrace to see the full trace)
Another example with a stacktrace is:
09:08:57 | Error java.lang.LinkageError: loader constraint violation: when resolving method "org.apache.http.impl.cookie.NetscapeDraftHeaderParser.parseHeader(Lorg/apache/http/util/CharArrayBuffer;Lorg/apache/http/message/ParserCursor;)Lorg/apache/http/HeaderElement;" the class loader (instance of groovy/lang/GroovyClassLoader) of the current class, org/apache/http/impl/cookie/BestMatchSpec, and the class loader (instance of org/codehaus/groovy/grails/cli/support/GrailsRootLoader) for resolved class, org/apache/http/impl/cookie/NetscapeDraftHeaderParser, have different Class objects for the type arser.parseHeader(Lorg/apache/http/util/CharArrayBuffer;Lorg/apache/http/message/ParserCursor;)Lorg/apache/http/HeaderElement; used in the signature

Running the command again, directly afterwards often succeeds.
I believe the problem is related to or caused by grails bundling a version of httpcore (4.2.4), but my desire to use a newer version (4.4.1)
I have tried excluding httpcore in the inherits('global') section of build config:
inherits('global') {
excludes 'httpcore'
}
as suggested by this answer How to exclude grails global dependency to no avail and also other specific dependencies suggested by this answer Grails --- loader constraint violation. I have also upgraded to the latest version of the release plugin.
The error happens as part of our Jenkins build process using grails 2.3.8 running on RedHat Linux 7 and JDK 1.7.0 (I have also tried a number of update versions to see if that is the problem)
