Is there a way we could build the oss version of the Elasticsearch from source code.
We have a requirement like, we have to build the Elasticsearch OSS from source code and use it instead of downloading it.
We would like to build with snapshot option false.
```auto
-Dbuild.snapshot=false
```
We get the below error.
./gradlew :distribution:archives:oss-no-jdk-linux-tar:assemble -Dbuild.snapshot=false
FAILURE: Build failed with an exception.
- Where:
Build file '/local/ES/elasticsearch/x-pack/plugin/core/build.gradle' line: 85
- What went wrong:
A problem occurred evaluating project ':x-pack:plugin:core'.
> Property license.key must be set for release build
- Try:
