Question

我正在将build.xml作为1 Ant Build运行。

我在机器上安装了jdk和jre 1.7.0_80;这是控制台日志：

Buildfile: C:\Users\Alessandro\workspace\cqwebapp\build.xml

clean:
      [delete] Deleting directory C:\Users\Alessandro\workspace\cqwebapp\build

init:
       [mkdir] Created dir: C:\Users\Alessandro\workspace\cqwebapp\build
       [mkdir] Created dir: C:\Users\Alessandro\workspace\cqwebapp\build\classes
