> Performance: The implementation of DefaultClassAnalyzer unnecessarily scans
> jar files bodies

> Key: MSHARED-307
> URL: https://jira.codehaus.org/browse/MSHARED-307
> Project: Maven Shared Components
> Issue Type: Bug
> Components: maven-dependency-analyzer
> Affects Versions: maven-dependency-analyzer-1.4
> Reporter: Victor Bronstein
> Assignee: Olivier Lamy
> Fix For: maven-dependency-analyzer-1.5
>
>
> The contract of the method is to provide a list of classes given a URL. In
> case of JAR files it would be enough to use JarFile#entries. However, since
> the implementation delegates to ClassFileVisitorUtils using an implementation
> of the visitor, the JAR files are being read completely, including the
> streams of the individual classes.
> This is a considerable performance hit. Specifically, in our project we have
> vast amount of Maven modules and do a dependency validation for them. By
> replacing the current implementation with one that uses JarFile#getEntries we
> were able to reduce the build time by 4 minutes.
