Strange, that looks like it ought to be just the job, but with
build.dir=build
build.xsltdoc.dir=${build.dir}/xsltdoc
build.xsltdoc.config=${build.xsltdoc.dir}/XSLTdocConfig.xml
dist.dir=dist
dist.xsltdoc.dir=${dist.dir}/xsltdoc
src.dir=src
then
<relpath property="xsltdoc.config.target"
base="${build.xsltdoc.config}" file="${dist.xsltdoc.dir}"/>
<relpath property="xsltdoc.config.source"
base="${build.xsltdoc.config}" file="${src.dir}"/>
results in
xsltdoc.config.target=../../../dist/xsltdoc
xsltdoc.config.source=../../../src
which is one "../" too many in each case :-(
A bug in FileUtils.getRelativePath, perhaps?
<relpath property="relpath.test" base="${build.xsltdoc.dir}/1"
file="${build.xsltdoc.dir}/2"/>
<echo message="relpath.test=${relpath.test}"/>
or even
<relpath property="relpath.test" base="1" file="2"/>
both display
relpath.test=../2
when I'd have expected just "2".
