How to install dex2jar
Dex2jar is developer utility. What follows is background, not a walkthrough. The authoritative version always lives with the project's own team.
Paths onto a machine
Expect differences between platforms. The same project may reach one system through a package index and another through a source build.
Who is behind it
Day-to-day direction belongs to the maintainers. They set the roadmap, cut releases, and decide which platforms stay supported.
Worth confirming early
Start from the support matrix. It narrows over time, and assumptions made years ago often no longer hold.
If something looks wrong
Surprises here are rarely the project's fault. Ordering inside the environment decides which copy wins, and that ordering is easy to get wrong.
What this domain is
Only text is published from this domain. Each project remains exactly where its authors put it.
Where things commonly go wrong
The most frequent surprise is a version that resolves somewhere unexpected. Check which copy is actually being picked up before assuming the project itself misbehaves.
