java - 从源代码构建 Freemarker

Question

我正在大学从事开源软件的安全项目。我正在尝试从源代码构建 freemarker，但遇到了一些问题。我在网上可以找到的所有内容都表明，在根目录中简单运行“ant”就应该构建项目。唯一的要求是你安装了 ant v1.7.0，我也是这么做的。

当我进入根目录并输入“ant”时，我得到以下输出:

Buildfile: build.xml

init:

_autoget-deps:

update-deps:
     [echo] Getting dependencies...
     [echo] -------------------------------------------------------

BUILD FAILED
/media/osr/runs/java/freemarker/freemarker/trunk/freemarker/build.xml:64: The following error occurred while executing this line:
/media/osr/runs/java/freemarker/freemarker/trunk/freemarker/build.xml:567: The following error occurred while executing this line:
/media/osr/runs/java/freemarker/freemarker/trunk/freemarker/build.xml:575: Problem: failed to create task or type antlib:org.apache.ivy.ant:settings
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.

This appears to be an antlib declaration. 
Action: Check that the implementing library exists in one of:
        -/usr/share/ant/lib
        -/home/murrayj/.ant/lib
        -a directory added on the command line with the -lib argument

build.xml 没有默认目标。试试这个吧

ant compile

编辑:更改目标
