(BUG): (building in java for testing purposes takes too much time)

[Maayanshani25]

Describe the bug

The recent changes introduced in PR #2879 modified the Java build process, making it only possible to build with the --release option. This build process now takes 3-4 minutes, which is unnecessary for testing purposes.

Suggested Fix
Reintroduce two separate build options:

• all - for testing purposes.
• allRelease - for optimized builds.

Expected Behavior

The build time should be reduced by at least half or more, especially for testing purposes, to improve efficiency and productivity.

Current Behavior

The build process takes excessive time and always runs in release mode, which is unnecessary for testing purposes.

Possible Solution

1. Review the changes introduced in PR #2879 to understand the build process modification.
2. Extract the two build options (All and AllRelease) from the original implementation to allow faster builds for testing purposes.
3. Update the developer.md file with clear instructions on how to use the two build options:
   • all: For testing purposes (faster builds).
   • allRelease: For optimized builds.

LGTM, short build times are important. Please drive it to completion

95% of time of java client compilation = rust code compilation
Debug configuration isn't significantly faster than release. The delta is lower than measurement precision.
If you want to get builds faster in CI - use caches (#771)

@Yury-Fridlyand I agree, as you know, what blocked us from caching until now?
I see a challenge with cases where we need to rebuild on rust changes of proto. But I'm sure we can easily solve that.
Something else?
Why didn't it enter into 1.3 CD improvements? Let at least push it into 1.4.

Nothing. I afraid such task doesn't fit our scope and release deadlines.
I'm happy to do that once I have time. Wanted to do that > year ago
