Ant 简明教程
Ant - Using Command Line Arguments
Ant 可以轻松读取命令行参数,以便将数据传递给其任务。
Commnd Line Arguments Options
ant [options] [target [target2 [target3] ...]]
Options:
-help, -h print this message and exit
-projecthelp, -p print project help information and exit
-version print the version information and exit
-diagnostics print information that might be helpful to diagnose or report problems and exit
-quiet, -q be extra quiet
-silent, -S print nothing but task outputs and build failures
-verbose, -v be extra verbose
-debug, -d print debugging information
-emacs, -e produce logging information without adornments
-lib <path> specifies a path to search for jars and classes
-logfile <file> use given file for log
-l <file> ''
-logger <classname> the class which is to perform logging
-listener <classname> add an instance of class as a project listener
-noinput do not allow interactive input
-buildfile <file> use given buildfile
-file <file> ''
-f <file> ''
-D <property>=<value> use value for given property
-keep-going, -k execute all targets that do not depend on failed target(s)
-propertyfile <name> load all properties from file with -D properties taking precedence
-inputhandler <class> the class which will handle input requests
-find <file> (s)earch for buildfile towards the root of
-s <file> the filesystem and use it
-nice number A niceness value for the main thread:1 (lowest) to 10 (highest); 5 is the default
-nouserlib Run ant without using the jar files from ${user.home}/.ant/lib
-noclasspath Run ant without using CLASSPATH
-autoproxy Java 5+ : use the OS proxies
-main <class> override Ant's normal entry point
我们将使用 -Dproperty 将变量传递给构建任务。
Example
使用以下内容创建一个 src 文件夹和 text1.txt 文件 −
This is a sample text written in 2021.
使用以下内容创建 build.xml −
<?xml version="1.0"?>
<project name="sample" basedir="." default="copy">
<target name="copy">
<copy todir="${dest.dir}" filtering="true">
<fileset dir="${src.dir}"/>
</copy>
</target>
</project>
Output
此处我们使用 src.dir 和 dest.dir 属性,但并未对其进行定义。我们将使用命令行参数来传递这些属性。在上述构建文件中运行 Ant 时,将生成以下输出 −
F:\tutorialspoint\ant>ant -Dsrc.dir=src -Ddest.dir=build
Buildfile: F:\tutorialspoint\ant\build.xml
copy:
[copy] Copying 1 file to F:\tutorialspoint\ant\build
BUILD SUCCESSFUL
Total time: 0 seconds
F:\tutorialspoint\ant>
查看复制到 build 文件夹的文件的内容。
