Question 1

How to check if a version is stable using Semver4j?

Accepted Answer

Use the isStable() method on a Semver object, which returns true if the major version is greater than 0 and there are no pre-release identifiers. For example, new Semver("1.2.3").isStable() returns true.

Question 2

Semver4j vs Apache Maven's version range parsing?

Accepted Answer

Semver4j provides stricter SemVer compliance and supports multiple range formats (NPM, CocoaPods, Ivy) out of the box, whereas Maven's version parsing is more limited to Maven-specific syntax and lacks built-in support for tilde or caret ranges.

Question 3

How to increment a patch version programmatically in Semver4j?

Accepted Answer

Call the withIncPatch() method on a Semver object to immutably create a new version with the patch incremented. For instance, new Semver("1.2.3").withIncPatch() returns "1.2.4".

Question 4

Does Semver4j handle build metadata in comparisons?

Accepted Answer

Yes, but build metadata is ignored in equivalent comparisons using isEquivalentTo(), while exact matches with isEqualTo() consider build metadata. This aligns with the SemVer spec where build metadata does not affect version precedence.

Question 5

How to create a custom range processor for a proprietary format?

Accepted Answer

Implement the Processor interface, override the process() method to handle your format, and use CompositeProcessor to combine it with built-in processors. The README provides an example with a CustomProcessor class.

Question 6

Is Semver4j actively maintained since it's a fork?

Accepted Answer

Yes, the README states it's an active fork of the original unmaintained library, with CI badges and recent releases (e.g., version 6.0.0), indicating ongoing development and community support.
