/var/jenkins_home/workspace/mydep/build.xml:12: Problem: failed to create task or type antlib:com.salesforce:deploy
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:
-/var/jenkins_home/tools/hudson.tasks.Ant_AntInstallation/Ant/lib
-/var/jenkins_home/.ant/lib
-a directory added on the command line with the -lib argument
将 Antlib.jar 文件添加到 Ant_Home/lib 文件夹中，然后重试。
