rake install throws NoMethodError: undefined method `[]' for nil:NilClass
Additional information which could be helpful if relevant to your issue:
Code example (inline, gist, or repo)
rake neo4j:install[community-latest,dev] --trace
Runtime information:
Neo4j database version:
neo4j
gem version: 7.0.13
neo4j-core
gem version: 6.1.4
The error is occuring in server_manager.rb line 269:
def server_version
kernel_jar_path = Dir.glob(@path.join('lib/neo4j-kernel-*.jar'))[0]
kernel_jar_path.match(/neo4j-kernel-([\d\.]+)\.jar$/)[1]
end
The second line assumes that the kernel_jar_path is neo4j-kernel-{version}.jar when, in my case, was actually neo4j-kernel-api-{version}.jar.
The call to match returns nil and throws an error when looking for the [1] index. A solution to this would be to build a better regex that takes this into account. I'm not a regex expert so I wouldn't presume to provide an example but I feel this would be fairly trivial to someone with decent competency in regex string matching.
have you found a solution to this? I am having the same issue.
