Ant はもはや ant の投稿を見つけることができず、マシン上で何かを変更したことを覚えていないので当惑しています。
$ ant -f ./build-ivy.xml
Buildfile: ./build-ivy.xml
[taskdef] Could not load definitions from resource net/sf/antcontrib/antlib.xml. It could not be found.
BUILD FAILED
/var/lib/jenkins/jobs/Lakshmi-MySQL/workspace/build-ivy.xml:41: Problem: failed to create task or type antlib:org.apache.ivy.ant:settings
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.
No types or tasks have been defined in this namespace yet
This appears to be an antlib declaration.
Action: Check that the implementing library exists in one of:
-/usr/share/ant/lib
-/var/lib/jenkins/.ant/lib
-a directory added on the command line with the -lib argument
これで、ant-contrib jar ファイルが (以前と同様に)/var/lib/jenkins/.ant/lib読み込まれ、ユーザーが読み取ることができるようになりました。
