從Date到String	DateFormat df = new SimpleDateFormat("yyyy-MM-dd"); Date d = new Date(); String dstr = Df.format(d);
從String到日期	DateFormat df = new SimpleDateFormat("yyyy-MM-dd"); Date d = df.parse("2014-02-19");
從date到calendar	Calendar cd1 = Calendar.getInstance(); Date sd1 = df.parse(startDate);         cd1.setTime(sd1); 如： startDate="2014-02-19";
從calender到Date	Calendar cd1 = Calendar.getInstance(); Date d = cd1.getTime();

格式化Date	DateFormat df = new SimpleDateFormat("yyyy-MM-dd"); String dstr = df.format(new Date());
格式化Calendar	DateFormat df = new SimpleDateFormat("yyyy-MM-dd"); Calendar cd1 = Calendar.getInstance(); String dstr = df.format(cd1.getTime());
格式化日期字符串	DateFormat df = new SimpleDateFormat("yyyy-MM-dd"); Date d = df.parse("2014-02-19"); DateFormat df1 = new SimpleDateFormat("MM-dd"); String dstr2 = df1.format(d);

  <target name="war.import" depends="svn.task,war.name">
    <echo>A: ${war.name}</echo>
  </target>

有時用

        <target name="war.name">

                <echo>
                        task war.name need to pass 4 parameters:
                        project.name
                        release.version
                        deploy.type
                </echo>

                <property name="war.name" value="${project.name}-${release.version}_${deploy.type}-${today}-${build.number}.war"/>
                <property name="war.file" value="${bin.dir}/${war.name}"/>

                <property name="war.md5.name" value="${war.name}.MD5"/>
                <property name="war.md5.file" value="${bin.dir}/${war.md5.name}"/>

                <echo>
                |-------------------------------------------------------------------------------|
                war.name        : ${war.name}
                war.file        : ${war.file}
                war.md5.name    : ${war.md5.name}
                war.md5.file    : ${war.md5.file}
                |-------------------------------------------------------------------------------|
                </echo>

        </target>

那么第一種調用方法，就能正確取得war.name屬性的值，而第二種調用就不能。所以建議盡可能的使用depends進行任務調用。

區別在細微的地方，不過也值得注意。

紅色字體的部分是調用了另外一個build文件中的任務。用的是ant call的方式調用的。
綠色字體部分引入的是另外一個build文件的路徑。

通過這種方式，可以把不同類型功能的任務放在單一的文件中。

Ant Task Dependency Graphs

by Jeanne Boyarsky

When inheriting an Ant build file to maintain, it is useful to get a feel for the flow and structure. Sketching the dependencies between targets is a useful way to do this. While it is time consuming to do so by hand, there are a number of tools to help.

I tried three different tools to generate the output. All of them generate a .dot file which needs to be run through the Graphviz tool to be converted to a useful format. Graphviz can covert to all image formats among many others. Each tool is described below with an example of how to call it. I've also included two sample images: from our build script to Pick Winners in the weekly book/software promotion and a contrived example designed to show how antCall and forEach work.

1. Ant2Dot - Ant2Dot is an XSLT file that converts your Ant build file into a .dot file. Each target becomes a rectangle and dependencies between targets are shown. The instructions for using it are a bit old and only apply to Java 1.3 and 1.4. They don't work on Java 5/6 without modification. The website lists a "to do" for adding support for Ant 1.6's import and subant features. Similarly, 1.7 features aren't supported yet. Ant2Dot is good for simple build files, but doesn't scale up to handle use advanced features. Running was as simple as downloading a stylesheet and running the command:

   C:\j2re1.4.2_03\bin\java org.apache.xalan.xslt.Process
   			-IN build.xml -XSL ant2dot.xsl -OUT build.dot

   Output of JavaRanch's book promotion pick a winner dependency structure and a contrived sample:
   
2. Vizant - Vizant is a Java library that creates a .dot file by using a SAX parser on your Ant build file. Each target becomes an oval and dependencies between targets are shown. Vizant supports antcalls and allows you to drill down to generate only part of the build tree. You can also drill down to show part of your build tree. Vizant was easy to use. I wanted the dependency ordering so continued looking for a library to meet my needs. In order to run Vizant, you need to download a jar containing the source and build it using Ant. They provide the build.xml to do so. Since this is a library for Ant documentation, it is reasonable to assume people know how to run Ant. You also call it through a simple Ant build file:

   <?xml version="1.0"?>
   <project name="Vizant" basedir="." default="vizant">
   	<taskdef name="vizant"
   		classname="net.sourceforge.vizant.Vizant"
   		classpath="build/vizant.jar" />
   
   	<target name="vizant">
   		<vizant antfile="build.xml" outfile="build.dot" uniqueref="true" />
   	</target>
   
   </project>

   Output of JavaRanch's book promotion pick a winner dependency structure and a contrived sample:
   
3. Grand - Grand is also a Java library that creates a .dot file. It takes a different approach and actually creates the Ant directory structure using Ant's Java libraries. It can support anything in your classpath including ant-contrib and Ant 1.6's import feature. The logic doesn't capture the subtleties of Ant-Contrib like the forEach loop though. The graph is a bit more detailed. The default target is a yellow hexagon. Targets with a description are marked in blue so you can show entry points. The remaining targets are shown as ovals. You can also drill down to show part of your build tree. You can use a Grand UI tool instead of the dot file, but I wasn't able to get the UI. Like Ant2Dot, dependencies are numbered. Grand was as easy to use as Vizant. They provide you with a jar for download. You call it through a simple Ant build file adding any other jars used to the classpath:

   <?xml version="1.0"?>
   <project name="Grand" basedir="." default="grand">
   
   	<typedef resource="net/ggtools/grand/antlib.xml" classpath="grand.jar" />
   
   	<target name="grand">
   		<grand output="grand-build.dot" buildfile="build.xml" />
   	</target>
   
   </project>

或者是如下格式

//

//

那么如何一次刪除所有java文件中的所有注釋呢？

通過sed的三次匹配操作，進行刪除操作。最后一個操作刪除所有的空行。

以上操作，只做刪除操作，并不修改文件。如果想直接對文件內容操作，可以用：

find . -name *.java -exec sed -i  -e '/\*/d' -e '/\/\//d' -e '/^\s*$/d' {} \;
