Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Steep learning curve for new users

   JavaParser's API is complex and requires a deep understanding of Java syntax and Abstract Syntax Trees (AST).

2. 02

   Limited documentation and examples

   The official documentation lacks comprehensive tutorials and real-world usage examples, making it difficult for developers to quickly get up to speed.

3. 03

   Performance issues with large codebases

   Parsing and analyzing large Java projects can be slow and resource-intensive, leading to long processing times and high memory usage.

4. 04

   Community support is not extensive

   While being open source, the community around JavaParser is relatively small compared to other popular tools, which can result in slower issue resolution and fewer contributions.

What it does well

• Supports Java versions from 1 to 25

• Generates Abstract Syntax Trees (AST) for code analysis

• Enables static code analysis and transformations

• Extensive documentation and community support
