问题描述
我在哪里,我创建了几个JAR文件的zip文件和清单Ant文件。无论是ZIP和清单引用同一个库,但略有不同的方式。如果可能的话,我想引用结合的文件,而不是明确地写他们两次,并希望能在这两项任务的参考同步。下面是我目前做的一个例子。
I have an Ant file where I am creating a zip file and a manifest for several JAR files. Both the zip and the manifest reference the same libraries, but in slightly different ways. If possible I would like to combine the references to the files instead of explicitly writing them twice and hoping the references in both tasks sync up. Below is an example of what I am currently doing.
<target name="zip" depends="default">
<zip destfile="${dist.dir}/${project.name}_v${project.version}.zip">
<zipfileset prefix="lib" dir="lib/Dom4J" includes="*.jar"/>
<zipfileset prefix="lib" dir="lib/GSON" includes="*.jar"/>
<zipfileset prefix="lib" dir="lib/Guava" includes="*.jar"/>
<!-- ... A bunch more (Note I don't want everything
in the lib directory, just certain subfolders
within the lib directory which are explicitly
listed here like GSON. -->
</zip>
</target>
<target name="createManifest">
<!-- Hard code the classpath by hand and hope
they sync up with the zip task -->
<property name="mfClasspath"
value="dom4j-1.6.1.jar gson-2.1.jar guava-11.0.2.jar" />
<!-- Code to use the mfClasspath when creating the manifest
omitted for brevity -->
</target>
我想最好想有一个文件集
一些,我可以在这两个任务引用。需要注意的是清单不包含任何文件夹/路径。清单只包含在拉链
任务中提到的目录中发现的JAR文件。
What I would ideally like to have is a fileset
of some sort that I could reference in both tasks. Note that the manifest does not contain any folders/paths. The manifest only contains the JAR files found within the directories mentioned in the zip
task.
推荐答案
您是对的。你可以用一个共同完成这个文件集
由两个拉链
和 createManifest $共享C $ C>任务。对于
拉链
任务,将文件复制到一个临时位置,然后压缩他们。
You are right. You can accomplish this with a common fileset
shared by both the zip
and createManifest
tasks. For the zip
task, copy the files to a temporary location and then zip them up.
对于 createManifest
任务,用字符替换,从路径删除文件夹。字符替换策略在讨论在Ant属性 ,则可以通过使用的。
For the createManifest
task, use character replacement to remove the folders from the paths. Character-replacement strategies are discussed in "Replacing characters in Ant property." If you have Ant-Contrib, you can simplify the character-replacement algorithm below by using the PropertyRegex Ant task.
<project default="all">
<fileset id="jars" dir=".">
<include name="lib/Dom4J/dom4j-1.6.1.jar" />
<include name="lib/GSON/gson-2.1.jar" />
<include name="lib/Guava/guava-11.0.2.jar" />
</fileset>
<target name="zip">
<copy todir="tmp.dir" flatten="true">
<fileset refid="jars" />
</copy>
<zip destfile="example.zip">
<zipfileset dir="tmp.dir" prefix="lib" />
</zip>
<delete dir="tmp.dir" />
</target>
<target name="createManifest">
<property name="jars.property" refid="jars" />
<echo message="${jars.property}" file="some.tmp.file" />
<loadfile property="mfClasspath" srcFile="some.tmp.file">
<filterchain>
<tokenfilter>
<replaceregex pattern="(?:[^;/]+/)+?([^;/]+\.jar)"
replace="\1" flags="g" />
<replacestring from=";" to=" " />
</tokenfilter>
</filterchain>
</loadfile>
<delete file="some.tmp.file" />
</target>
<target name="all" depends="zip, createManifest">
<echo message="$${jars.property} = "${jars.property}"" />
<echo message="$${mfClasspath} = "${mfClasspath}"" />
</target>
</project>
当我执行上面的Ant构建,下面是输出到控制台:
When I executed the above Ant buildfile, the following was output to the console:
Buildfile: /workspace/StackOverflow/build.xml
zip:
[zip] Building zip: /workspace/StackOverflow/example.zip
[delete] Deleting directory /workspace/StackOverflow/tmp.dir
createManifest:
[delete] Deleting: /workspace/StackOverflow/some.tmp.file
all:
[echo] ${jars.property} = "lib/Dom4J/dom4j-1.6.1.jar;lib/GSON/gson-2.1.jar;lib/Guava/guava-11.0.2.jar"
[echo] ${mfClasspath} = "dom4j-1.6.1.jar gson-2.1.jar guava-11.0.2.jar"
BUILD SUCCESSFUL
Total time: 675 milliseconds
此外, example.zip 的包含以下项目:
- 的的lib / dom4j的-1.6.1.jar 的
- 的的lib / GSON-2.1.jar 的
- 的的lib /番石榴11.0.2.jar 的
- lib/dom4j-1.6.1.jar
- lib/gson-2.1.jar
- lib/guava-11.0.2.jar
