## プロジェクトの歴史と使われ方

fastjar is a free-software implementation of the Java JAR command, paired with grepjar, that survived as a small Unix package because it let GCC/GNU Java-era systems create and inspect JAR archives without depending on Sun's proprietary toolchain.

### プロジェクトの歴史

The Savannah project page records fastjar as a non-GNU project registered on March 21, 2006, with GPL-2.0-or-later licensing and a CVS source repository. GCC hosted a manual titled Guide to GNU jar utilities, documenting fastjar and grepjar as command-line utilities.

### 採用の歴史

fastjar's adoption has been historical and distribution-driven rather than community-growth driven. It appears in Unix package managers as a compatibility tool for older Java/GNU Classpath and GCC Java workflows, while modern Java installations generally provide jar through the JDK.

### 使われ方

The GCC manual describes fastjar as the tool to invoke for JAR archive operations and grepjar as the companion search utility. In practice it is installed when a small, standalone jar-compatible command is needed in old build recipes or minimal packaging environments.

### パッケージ好きにとっての重要性

Package maintainers care about fastjar mostly as fossil infrastructure: it is a reminder of the period when free Java tooling had to replace proprietary pieces one command at a time, and it remains packaged because old build graphs sometimes still name fastjar explicitly.

### タイムライン

- 2006: fastjar project registered on Savannah.
- 2006: GCC 4.0-era online docs published the fastjar and grepjar manual.
- 2026: Homebrew still packages fastjar 0.98 as an implementation of Sun's jar tool.

### Related projects

- Sun/Oracle jar is the tool fastjar implements.
- grepjar is shipped and documented as fastjar's companion utility.
- GNU Classpath and GCC Java-era packaging are the ecosystem context in which fastjar mattered most.
