(solved) Maven: CompilationFailureException: Compilation failure
JAVA_HOME
が設定されていなかったというありがちなやつですが、次に同じことが起こったときに手間取らないように覚書。
状況
対象: Apache PDFBox(GitHub mirror) 2.0.21
README にしたがって mvn clean install
を実行するとコンパイルで失敗する。

今回ヒントになったのはこのあたり:

javac のパスが
[DEBUG] (f) executable = ${env.JAVA_HOME}/bin/javac
となっていて、環境変数 JAVA_HOME
が期待されているようだったので、
JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64 mvn clean install
のように指定したらコンパイルできるようになった。
バージョンが 1.6 となっているのも気にはなって、たぶん正しく指定した方がいいんだろうけどそっちは修正しなくてもよかった。理由は不明。
ついでにメモ。
compile
ゴールのヘルプ表示コマンド:
mvn compiler:help -Ddetail=true -Dgoal=compile
