當我嘗試使用ant構建我的項目時出現錯誤。下面是構建文件：

這裏是Ant構建日誌（誤差在底部）：

Compiling 6 source files to C:\Users\gbaldeck\Google Drive\Work\LearningAS7\GrahamsProjClient\dist
Unresolvable reference ${lib.classpath} might be a misuse of property expansion syntax.

BUILD FAILED (total time: 0 seconds)
是什麼原因造成這種情況？我沒有看到我的路徑設置有什麼問題。
是這樣！謝謝。 – Graham
