verifyJigEnvironmentでOKとなるにもかかわらずjigReportでエラーとなる

[e-yamane]

不具合の内容

dotコマンドへのパスが相対パスの場合verifyJigEnvironmentでOKとなるにもかかわらずjigReportでcommand not foundになります。
（Graphvizはインストールしてません。独自にdotコマンドを作ってDockerコンテナへの処理移譲を想定してます）

環境

• JIGのバージョン: 2020.6.2.1
• 実行方法: GradlePlugin
• Javaのバージョン: openjdk version "11.0.7" 2020-04-14 LTS
• OS: Mac OS Catalina 10.15.5

再現手順

% ./dot
zsh: no such file or directory: ./dot
% ./gradlew verifyJigEnvironment
(省略)
> [dot] command not found
(省略)
BUILD FAILED
% touch dot
% chmod +x dot
% PATH=$PATH:./
% ./gradlew verifyJigEnvironment
BUILD SUCCESSFUL
% ./gradlew jigReport
(省略)
Caused by: java.io.IOException: /bin/sh: dot: command not found
