ノンロード依存のタスククラスによるAntビルドの失敗

Question

Buildfile: /.../build.xml

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

...私はすべての推奨ディレクトリをチェックしましたが、まだビルドの失敗が続きます。私が調べた特定のJAR 'ant.jar'はクラス 'Task'を持ち、 '/Applications/eclipse/plugins/org.apache.ant_1.7.1.v20090120-1145/lib'にあります。ディレクトリ。このクラスパスをbuild.xmlに手動で追加する必要がありますか？ここに私のbuild.xmlは次のとおりです。

あなたは、Eclipse内からアリを開始していますか？

{Run | External Tools Configuration ...}をクリックすると、Classpathタブに "Ant Home"が含まれます。展開後、有効なファイルを指していますか？
