我想替换基于操作系统的现有jar的路径。
下面是一些类似的东西:
在windows中: C:/apps/workspace/libs/rpm.jar
在unix中: /user-id/projectname/libs/rpm.jar
有没有办法从C:/apps/workspace/libs/rpm.jar中删除C:/apps/workspace/libs。
将我的问题编辑为:
谢谢Liv,但我有很多这样的库。现在,我正在维护一个名为"build.start.properties“的文本文件,所有的库都是这样的
/gwt/X/2.1.0/gwt-servlet.jar
/gwt/X/2.1.0/gwt-user.jar /gwt/X/2.1.0/gwt-dev.jar
/gwt/X/2.1.0/gwt-soyc-vis.jar /log4j/X/1.2.15/log4j-1.2.15.jar /GWT_LOG/X/3.0.3/gwt-log-3.0.3.jar /GWT_math/X/2.1/GWT-math 2.1.jar/GWT_math/X/2.1/GWT-math server-2.1.jar /GWT_Commons_Logging/X/0.3/GWT-commons-logging/gwt-commons-logging-0.3.jar
/GWT_Commons_Logging/X/0.3/GWT-commons-logging/gwt-commons-logging-service-0.3.jar
并使用以下目标将它们加载到classptah
<loadfile property="jars.list.property" srcfile="mybuild/build.start.properties">
<filterchain>
<expandproperties />
<striplinecomments>
<comment value="#" />
</striplinecomments>
<tokenfilter>
<ignoreblank />
</tokenfilter>
<prefixlines prefix="," />
<striplinebreaks />
</filterchain>
</loadfile>
<filelist id="build.libs" dir="" files="${jars.list.property}" />
<pathconvert targetos="unix" property="build_unix.libs" refid="build.libs">
<map from="C:" to="${unix.xenv}" />
<map from="" to="${unix.xenv}" />
</pathconvert>
<pathconvert targetos="windows" property="build_windows.libs" refid="build.libs">
<map from="C:" to="${windows.xenv}" />
<map from="" to="${windows.xenv}" />
</pathconvert>
<path id="build.classpath.id">
<pathelement path="${build_windows.libs}" />
<pathelement path="${build_unix.libs}" />
</path>
<echo message="Build Libraries classpath: ${toString:build.classpath.id}" />
</target>从上面的目标看,build.classpath.id看起来像/gwt/X/2.1.0/gwt-servlet.jar:/gwt/X/2.1.0/gwt-user.jar:/gwt/X/2.1.0/gwt-dev.jar:/gwt/X/2.1.0/gwt-soyc-vis.jar:/log4j/X/1.2.15/log4j-1.2.15.jar:/GWT_LOG/X/3.0.3/gwt-log-3.0.3.jar:GWT_MATH/X/2.1/gwt-math-2.1.jar:/GWT_MATH/X/2.1/gwt-math-server-2.1.jar:/GWT_Commons_Logging/X/0.3/GWT-commons-logging/gwt-commons-logging-0.3.jar:/GWT_Commons_Logging/X/0.3/GWT-commons-logging/gwt-commons-logging-service-0.3.jar
当我在unix上工作时,我只需要从文件"build.start.properties“中提取jar名称,并像这样更新路径。
/WebContent/WEB_INF/lib/gwt-servlet.jar:/WebContent/WEB_INF/lib/gwt-user.jar:/WebContent/WEB_INF/lib/gwt-dev.jar:/WebContent/WEB_INF/lib/gwt-soyc-vis.jar:/WebContent/WEB_INF/lib/log4j-1.2.15.jar:/WebContent/WEB_INF/lib/gwt-log-3.0.3.jar:/WebContent/WEB_INF/lib/gwt-math-2.1.jar:/WebContent/WEB_INF/lib/gwt-math-server-2.1.jar:/WebContent/WEB_INF/lib/gwt-commons-logging-0.3.jar:/WebContent/WEB_INF/lib/gwt-commons-logging-service-0.3.jar

总是使用相对路径,这样你就不会依赖于给定位置的库和底层操作系统。
虽然这并没有完全满足你的要求,但从长远来看,这个建议会对你有所帮助。此外,如果可能,请使用Ivy + Ant (或Maven)来管理依赖项。

您可以使用ant任务--下面的内容取自文档(http://ant.apache.org/manual/Tasks/condition.html):
<condition property="isMacOsButNotMacOsX">
<and>
<os family="mac"/>
<not>
<os family="unix"/>
</not>
</and>
</condition>https://stackoverflow.com/questions/5793332
