Maven Version (Java) Regex for JavaScript
/^([0-9]+)\.([0-9]+)\.?([0-9]*)(?:[.\-]([a-zA-Z][a-zA-Z0-9\-]*))?(?:[.\-]([0-9]+))?$/What this pattern does
This page provides a comprehensive, battle-tested regular expression for matching maven version (java), ported and verified for JavaScript. A rigorously tested regex reduces debugging time and protects your application from edge-case failures. The snippet below is ready to drop into your JavaScript project — whether you're validating in an Express middleware, a Next.js API route, or a client-side form.
Javascript Implementation
// Maven Version (Java)
// ReDoS-safe | RegexVault — Dev & Systems > SemVer
const mavenVersionJavaRegex = /^([0-9]+)\.([0-9]+)\.?([0-9]*)(?:[.\-]([a-zA-Z][a-zA-Z0-9\-]*))?(?:[.\-]([0-9]+))?$/;
function validateMavenVersionJava(input: string): boolean {
return mavenVersionJavaRegex.test(input);
}
// Example
console.log(validateMavenVersionJava("1.0")); // trueTest Cases

When to use this pattern
This pattern is drawn from the Dev & Systems > SemVer category and carries a ReDoS-safe certification. That matters for JavaScript developers because especially critical in long-running Node.js event loops where a ReDoS vulnerability can block the entire process. RegexVault audits patterns against known backtracking attack vectors, ensuring you have the necessary context before using this regex in a high-stakes production environment.
Common Pitfalls
1.0-SNAPSHOT is a special Maven concept meaning the development version preceding 1.0. SNAPSHOT versions should never be released to production repositories.
Technical Notes
Maven version ordering is complex and does not follow strict SemVer rules. Qualifiers like SNAPSHOT, RELEASE, alpha, beta, RC have defined ordering in Maven. Use Maven's own ComparableVersion for reliable comparison.
