Summary: pathelement 'ant.jar' of path 'tomcat.classpath' is
needless in build.xml
Product: Tomcat 6
Version: 6.0.20
Platform: PC
OS/Version: Linux
Status: NEW
Severity: trivial
Priority: P2
Component: Catalina
AssignedTo: dev@tomcat.apache.org
ReportedBy: qingyang...@qunar.com
following is the relevant parts of the 'build.xml' file:
<path id="tomcat.classpath">
<pathelement location="${ant.jar}"/>
<pathelement location="${jdt.jar}"/>
</path>
... ...
<target name="compile">
<javac srcdir="java" destdir="${tomcat.classes}"
debug="${compile.debug}"
deprecation="${compile.deprecation}"
source="${compile.source}"
target="${compile.target}"
optimize="${compile.optimize}"
excludes="**/CVS/**,**/.svn/**"
encoding="ISO-8859-1">
<!-- Comment this in to show unchecked warnings: <compilerarg
value="-Xlint:unchecked"/> -->
<classpath refid="tomcat.classpath" />
<exclude name="org/apache/naming/factory/webservices/**" />
</javac>
... ...
</target>
However, if you delete the first item (<pathelement location="${ant.jar}"/>) in
the path element whose id is 'tomcat.classpath', the target of 'compile' still
runs successfully, and if you invoke ant as "ant -v", you can see that
'ant.jar' has already been included in the classpath. For example, the
following is the output on my machine:
