从源代码构建Freemarker

Question

我在我的大学做一个开源软件的安全项目。我试图从源码建立freemarker，但我遇到了一些问题。我在网上找到的所有东西都表明，在根目录中运行'ant‘就可以构建项目。惟一的要求是您安装了ANTV1.7.0，我也是这样做的。

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

Answer 1

build.xml没有默认目标。试试这个吧

ant compile

编辑：更改了目标

Answer 2

您还需要Apache Ivy。我们已经改变了一段时间的构建过程；它现在使用Ivy而不是手动的依赖管理。

Answer 3

在Ubuntu/Debian上，安装Ivy还需要手动将其添加到ant类路径中。

虽然这可能不是最干净的方法1

sudo ln -s /usr/share/java/ivy.jar /usr/share/ant/lib/ivy.jar
