How to Compile Against a Fixed Version of Objectionary

When you compile your EO code, the compiler discovers which objects are “foreign” and tries to find them in Objectionary. It finds them, downloads, and then compiles locally. The problem is that the objects in Objectionary are not static: they get new versions very often. That’s why, in order to stabilize your build you may want to use their fixed versions.

Here is how, in your pom.xml (hash must include Git commit hash from objectionary/home):

<project>
  [...]
  <build>
    [...]
    <plugins>
      [...]
      <plugin>
        <groupId>org.eolang</groupId>
        <artifactId>eo-maven-plugin</artifactId>
        <configuration>
          <hash>0d94362</hash>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

If you use eoc, you can do it with the command line option:

$ eoc --hash=0d94362 compile
