I have a webapp to be ran on Tomcat6/JbossAS 5 and, for versioning purposes, I have several AND targets that will perform a set of operations to define a constant with version number and build datetime.
The targets perform the following:
- Delete the Release.java
- Copy the Release.template to Release.java with the versioning info properly set as a constant (public static final String)
The thing is that, the constant references are replaced on the code before compilation. For instance, where I have
log.debug("Release: " + Release.info);
I can see, using java decompiler, the following (let's assume that "TO_BE_DEFINED" is the initial value for Relase.info):
log.debug("Release: TO_BE_DEFINED");
The targets are the following:
<target name="build-config" >
<!-- config -->
<property name="project.name" value="MY PROJECT" />
<property name="release.prefix" value="MPROJECT" />
<property name="release.num" value="1.0" />
<property name="release.info.file.path" value="org/my/project/Release" />
<tstamp>
<format property="release.date" pattern="yyyy-MM-dd HH:mm:ss z" />
</tstamp>
<!-- end config -->
<property name="release.version" value="${release.prefix}-${release.num}" />
<property name="release.info" value="${release.version} ${release.date}" />
</target>
<target name="build-replace">
<filter token="release.info" value="${release.version} ${release.date}" />
<delete file="${src.dir}/${release.info.file.path}.java" />
<copy file="${src.dir}/${release.info.file.path}.template" tofile="${src.dir}/${release.info.file.path}.java" filtering="true" />
</target>
<target name="build-myproj-1.0.jar" depends="init,buil-config,build-replace,compile">
<mkdir dir="${dist.dir}"/>
<jar compress="true" jarfile="${dist.dir}/MPROJECT-1.0.jar">
<fileset dir="${build.classes.dir}"
excludes="META-INF/*.*, WEB-INF/classes/*.xml"
includes="**/*.class"
/>
<manifest>
<section name="${project.name}">
<attribute name="Release-Version" value="${release.version}" />
<attribute name="Release-Date" value="${release.date}" />
</section>
</manifest>
</jar>
</target>
and my class is defined as
public abstract class Release {
/** Release info */
public static final String INFO = "TO_BE_DEFINED";
}
I understand that this may be a little bit confusing and if I'm missing some information please feel free to ask
