Error when running `eoc --easy dataize` after adding the plugin to `pom.xml`

[morphqdd]

When I attempted to resolve this issue, I added the sodg plugin to pom.xml in the eoc source code, but when I attempted to run the integration tests from the itest folder, I encountered the following error:

@yegor256 Are there any developments in fixing this bug or other ways to build sodg? I am not a Java developer, so I cannot fix it myself

[morphqdd]

@yegor256 Take a look, please

[yegor256]

@morphqdd I can't reproduce this bug in the master :( It seems, this issue needs deeper investigation.
