2.1.5 release preparation

[akarnokd]

Note that there might be a couple of 2.1.5-RCx tags before this release in order to iron out the nebula-plugin free release process.

FYI: RC4 finally managed to release to maven central without errors: https://travis-ci.org/ReactiveX/RxJava/builds/282648040

cc Netflix team: RC-4 doesn't have <properties> in the pom.xml that 2.1.4 had:

 <properties>
    <nebula_Manifest_Version>1.0</nebula_Manifest_Version>
    <nebula_Implementation_Title>io.reactivex.rxjava2#rxjava;2.1.4</nebula_Implementation_Title>

    <nebula_X_Compile_Target_JDK>1.6</nebula_X_Compile_Target_JDK>
    <nebula_X_Compile_Source_JDK>1.6</nebula_X_Compile_Source_JDK>
  </properties>

I don't think someone consumes them though.

Another difference is that RC4 doesn't have META-INF/rxjava.properties in the jar that 2.1.4 has:

Manifest-Version=1.0
Implementation-Title=io.reactivex.rxjava2#rxjava;2.1.4
Implementation-Version=2.1.4
Built-Status=integration
Built-By=travis
Built-OS=Linux
Build-Date=2017-09-22_09:03:52
Gradle-Version=2.14
Module-Owner[email protected]
Module-Email[email protected]
Module-Source=
Module-Origin=https://github.com/ReactiveX/RxJava.git
Change=3e33000
Branch=3e3300049dff23b15fa7f6639c844615a0b76f81
Build-Host=testing-gce-49a1561b-b1d2-4225-9e33-fb4d4835d959
Build-Job=LOCAL
Build-Number=LOCAL
Build-Id=LOCAL
Created-By=1.8.0_144-b01 (Oracle Corporation)
Build-Java-Version=1.8.0_144
X-Compile-Target-JDK=1.6
X-Compile-Source-JDK=1.6

---

And final noticeable difference I see is that META-INF/MANIFEST.MF in the jar has different values of some keys that are most likely important for OSGI support:

• Bundle-Vendor was — ReactiveX, now — RxJava Contributors
• Import-Package was — org.reactivestreams;version="[1.0,2)", now — lots of inner RxJava packages

Plus it misses meta info like X-Compile-Target-JDK, X-Compile-Source-JDK, Change, Module-Origin, etc.

You can download files from maven central to make own comparison.

I don't know about the nebula properties, but we no longer use nebula. The rxjava.properties also looks like a copy of those nebula properties which RxJava itself never used. Android folks no longer have to fear the duplication of rxjava.properties I guess.

The manifest is controlled by this part of the build.
