Allow overriding gradle version to hardcode a specific version

[dakrone]

I work on a project that requires gradle 2.13 due to bugs introduced in later gradle versions, however, when I try to run the server I get:

Caused by: org.gradle.api.GradleException: Gradle 2.13 is required to build elasticsearch
    at build_da97v8nh3ew8kq4jfh1zxmavb.run(/home/hinmanm/es/elasticsearch/buildSrc/build.gradle:33)
    at org.gradle.groovy.scripts.internal.DefaultScriptRunnerFactory$ScriptRunnerImpl.run(DefaultScriptRunnerFactory.java:90)
    ... 83 more

Because it uses gradle 3.0 from the wrapper.

It would be great if there were a way to tell meghanada to use gradle from the $PATH rather than the gradle from the wrapper, so the version I need to use explicitly will work.

This is elasticsearch side problem.
Server support multi gradle version and detect your project gradle wrapper ./gradlew.
But elasticsearch does not provide gradle wrapper.
(see elastic/elasticsearch#13744 )

Supported override gradle version.

$ export MEGHANADA_GRADLE_VERSION=2.13

OR

$ java -jar path/to//meghanada.jar --gradle-version 2.13

@mopemope thanks for adding that option! It looks like the jar from https://dl.bintray.com/mopemope/meghanada/meghanada.jar is the older version that doesn't support that yet, any idea when it will be updated?

Thanks, I am able to use meghanada now!
