로드되지 않는 종속 작업 클래스로 인해 앤트 빌드가 실패했습니다.

BUILD FAILED 
/.../build.xml:43: Problem: failed to create task or type junit 
Cause: Could not load a dependent class org/apache/tools/ant/Task 
    It is not enough to have Ant's optional JARs 
    you need the JAR files that the optional tasks depend upon. 
    Ant's optional task dependencies are listed in the manual. 
Action: Determine what extra JAR files are needed, and place them in one of: 
    -/Applications/eclipse/plugins/org.apache.ant_1.7.1.v20090120-1145/lib 
    -/Users/cjwalsh/.ant/lib 
    -a directory added on the command line with the -lib argument 

Do not panic, this is a common problem. 
The commonest cause is a missing JAR. 

This is not a bug; it is a configuration problem

... 그리고 권장되는 모든 디렉토리를 검사했지만 아직 빌드 실패가 계속 발생합니다. 살펴본 특정 JAR 'ant.jar'에는 'Task'클래스가 있으며 '/Applications/eclipse/plugins/org.apache.ant_1.7.1.v20090120-1145/lib'파일에 있습니다. 예배 규칙서. 이 클래스 경로를 build.xml에도 수동으로 추가해야합니까? 다음은 내 build.xml입니다.

Eclipse 내에서 개미를 시작 했습니까?

{Run | External Tools Configuration ...}을 클릭하면 Classpath 탭에 "Ant Home"이 포함됩니다. 확장 후 유효한 파일을 가리 킵니까?
