Choosing a Version of PSL
Maven allows several ways to specify acceptable versions for dependencies. This page discusses the recommended options to specifying the PSL version to use.
Exact Version
If you are working on a paper or code that requires exact reproducibility, then you should specify an exact version of PSL.
For example:
<dependencies>
...
<dependency>
<groupId>org.linqs</groupId>
<artifactId>psl-cli</artifactId>
<version>2.1.0</version>
</dependency>
...
</dependencies>
Major Minor
If you want to get bug fixes without worrying about breaking changes, then you can specify a major and minor version while allowing the incremental (patch) version to grow.
For example:
<dependencies>
...
<dependency>
<groupId>org.linqs</groupId>
<artifactId>psl-cli</artifactId>
<version>[2.1,)</version>
</dependency>
...
</dependencies>
Major
If you want the latest stable code and can tolerate the occasional breakage, then you can specify just the major version.
For example:
<dependencies>
...
<dependency>
<groupId>org.linqs</groupId>
<artifactId>psl-cli</artifactId>
<version>[2,)</version>
</dependency>
...
</dependencies>
Canary
If you are doing development any are willing to accept potential bugs, broken builds, and API breakages, then you can use the canary build. See the working with canary page to get detail on how best to work with the canary build.
<dependencies>
...
<dependency>
<groupId>org.linqs</groupId>
<artifactId>psl-cli</artifactId>
<version>CANARY-2.2.1</version>
</dependency>
...
</dependencies>
