Building v2.3.5 from source fails


(Lukas Vlcek) #1

Hi,

I am trying to build Elasticsearch v2.3.5 from sources but I am running into build error:

The flow is pretty simple:

$ git clone https://github.com/elastic/elasticsearch.git
$ cd elasticsearch
$ git checkout v2.3.5
$ mvn clean package
// doing $ mvn clean package -DskipTests fails as well

Complete log can be seen here: https://gist.github.com/lukas-vlcek/fa9b33ec54e6d4c7a38a74f97a4b9601

Excerpt:

One interesting thing is that from ES 2.x it seems the tag commits point to -SNAPSHOT versions. See: https://github.com/elastic/elasticsearch/blob/v2.3.5/pom.xml#L9 or https://github.com/elastic/elasticsearch/blob/90f439ff60a3c0f497f91663701e64ccd01edbb4/pom.xml#L9

Why is that? Shall I modify pom.xml files and remove -SNAPSHOT manually before building final version?

May be I am reading something wrong in
https://github.com/elastic/elasticsearch/tree/v2.3.5#building-from-source or https://github.com/elastic/elasticsearch/blob/v2.3.5/TESTING.asciidoc?

Here it works (well, somehow, but the build fails to sign the Debian package, a failure which I expect)

Seems your Maven does not detect a JDK so it emits the message

[WARNING] Unable to autodetect 'javac' path, using 'javac' from the environment.

Maybe setting JAVA_HOME helps?

env | grep JAVA
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/Contents/Home

Yes, that's nasty. I reset the version manually by editing pom.xml.

@jprante good catch, thanks! After I changed from

JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/Home/jre
to
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/Home

the mvn clean package -DskipTests passed without any issues (not even running into issues with Deb package building, interesting you are running into it...).
