我在Red Hat Enterprise Linux Server 5.2 Beta（Tikanga）上使用Eclipse 3.2.0，并尝试使用Ant构建文件和属性文件创建项目。当我加载构建文件时，加载的唯一属性是$ {build.dir}，$ {bin.dir}和$ {dist.dir}。属性文件中的所有其他属性都不会加载。任何人都可以帮我确定为什么其他属性不会加载？请参阅下面的代码。
build.properties：
bin.dir=bin
build.dir=build
dist.dir=dist
src.dir=src
doc.dir=doc
config.dir=config
common.lib.dir=lib
reports.dir=reports
的build.xml：
tools.lib.dir=tools/lib
tools.etc.dir=tools/etc
findbugs.home.dir=tools/findbugs
findbugs.lib.dir=tools/findbugs/lib

答案 0 :(得分：-1)
简单回答是该文件不是您在此处粘贴的文件。找出错误的最简单方法是将以下内容粘贴到某处以查看加载的文件：
<property name="whatswrong" location="build.properties"/>
<echo>The absulute path of property file is ${whatswrong}/>
这是基于这样一个事实，即location属性总是会返回绝对路径。
ps：使用maven，因为你的构建脚本就像生命周期
