Add Maven Support

Original post
I can see some maven releases here:
https://bintray.com/nikola-ilo/maven/or-tools/view
Q: Why the releases are not continued? Are you guys planning to release a new version on maven?
A: Not done by Google LLC

For v8.0 we are migrating to use maven to create java package
Todo List:

These are actual contributed and we did not do it.
I will contact the author to see if we can transfer it to or-tools.

Thanks

I would definitely appreciate being able to integrate or-tools using Maven

Hello Punkeel,
It's on our to-do list to support Maven. Thank you.
Regards,
Driss

Any news ?

Maven support would be interesting...

hi all,

Yes I would like to provide a maven (gradle ? ivy ?) package for or-tools ASAP and ideas are welcome !

How I see it currently:
1.Have a clean and modern CMake project to replace Makefile (cf WIP mizux/cmake branch)
2. Have a gradle project with cpp-plugin/JNI to wrap libortools.so
3. Use gradle plugin "maven-publish'
4. Profit !

@dillonmabry our team has been using this: https://github.com/panavis/google-or-tools-maven. We hope that there will be an official release soon. @Mizux.

@amucunguzi

@amucunguzi thank you for working on this! I saw that https://github.com/panavis/google-or-tools-maven doesn't have a dependency for mac -- is that on it's way at all?

@suming

@suming My version #202 (comment) has all OS distributions available 👀

@magneticflux-

Yes, I've been using @magneticflux-'s version on OSX and it works fine.

@magneticflux-

@magneticflux- & @lalithsuresh thank you for the heads-up, I just tested it out and it's great. I can develop locally on OSX and deploy on Linux easily. Appreciate it!

@suming

@suming My version #202 (comment) has all OS distributions available 👀

Using this version currently with no issues, thanks for your support! Works as expected.

For those that had trouble running Makefile in order to install the jars follows a detailed set-up guide based on @magneticflux- 's solution:

Guarantee maven (mvn) executable folder (e.g. /bin) is on your classpath
Download binaries (version 8.0) for your OS at https://github.com/google/or-tools/releases/tag/v8.0. For Windows the link is https://github.com/google/or-tools/releases/download/v8.0/or-tools_VisualStudio2019-64bit_v8.0.8283.zip
Extract the zip file and run these 2 commands inside the folder:
mvn org.apache.maven.plugins:maven-install-plugin:2.5.2:install-file -Dfile="ortools-win32-x86-64-8.0.8283.jar" -DpomFile="pom-runtime.xml"
mvn org.apache.maven.plugins:maven-install-plugin:2.5.2:install-file -Dfile="ortools-java-8.0.8283.jar" -DpomFile="pom-local.xml"
Add the following dependencies to your project (in my case, to run or-tools over windows) :
<dependency> <groupId>com.skaggsm.ortools</groupId> <artifactId>ortools-natives-all</artifactId> <version>8.0.8283</version> <type>pom</type> </dependency> <dependency> <groupId>com.google.ortools</groupId> <artifactId>ortools-java</artifactId> <version>8.0.8283</version> </dependency> <dependency> <groupId>com.google.ortools</groupId> <artifactId>ortools-win32-x86-64</artifactId> <version>8.0.8283</version> </dependency>
Run a test file , calling first the loader and then setting up the solver:
@Test public void test(){ OrToolsHelper.loadLibrary(); MPSolver solver = MPSolver.createSolver("SCIP"); }

I'm not sure why you're installing both my distribution and the official one. You don't need both; mine has everything included and has extra extraction functionality.

This is the next step, but we need to test few things:

Is there a ticket for maven central publishing?

Is there a ticket for maven central publishing?

With the sunsetting of JCenter, this is more urgent for me in particular. I'm not keen on shouldering the cost of hosting large binaries myself going forward, so I'd like my solution to just depend on official binaries on Maven Central.

FYI, first 8.2 RC (8.2.9004)
https://search.maven.org/search?q=g:com.google.ortools
https://mvnrepository.com/artifact/com.google.ortools

note: I failed the linux artifact which is currently depending on GLIBC 2.33 (archlinux ^^;)

example usage: https://github.com/or-tools/java_or-tools/blob/6df2f03abe2b869f197eafe4c0846a376dbe04a0/pom.xml#L51-L59

@Mizux

@Mizux thanks! I just tested the Darwin version and it works.

note: I failed the linux artifact which is currently depending on GLIBC 2.33

Could you elaborate more on this?

If it helps, I'm getting an error about needing GLIBC 2.29 when running on Ubuntu 18.04.

java.lang.UnsatisfiedLinkError: /tmp/ortools-java7239044082451951181/linux-x86-64/libjniortools.so: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by /tmp/ortools-java7239044082451951181/linux-x86-64/libortools.so)

see #2520
TLDR the runtime has been built against GLIBC 33 (archlinux) need to build the package against an "older" Linux distro

This is great news, and we appreciate your hard work!

Question: Is there a solution to have this work with Docker? For example, it works fine for me locally but whenever I run my docker build it cannot find the JNI/Library resource files like it can when I run locally, it extracts and discovers them automatically with my Spring/Java build.

I am using JDK 11 and Maven if that helps.

Thank you!

@dillonmabry

@dillonmabry let's open a new issue with your docker issue.
note: You are not the only one with this feedback IIRC but I was never be able to reproduce it...
see: https://github.com/or-tools/java_or-tools/blob/main/Dockerfile and https://github.com/or-tools/java_or-tools/runs/2441985470?check_suite_focus=true
