KWON BYUNGCHANG created BIGTOP-4544:
---------------------------------------

             Summary: bigtop_toolchain: latest ant/maven versions not resolved due to HTML-escaped "&"
                 Key: BIGTOP-4544
                 URL: https://issues.apache.org/jira/browse/BIGTOP-4544
             Project: Bigtop
          Issue Type: Bug
            Reporter: KWON BYUNGCHANG


bigtop_toolchain is intended to install the latest matching ant (1.9.x) and maven (3.9.x) versions:

{code}
# maven.pp
$mvnversion = latest_maven_binary("3.9.[0-9]*")

# ant.pp
$ant = latest_ant_binary("1.9.[0-9]*")
{code}

But both resolver functions fetch the archive.apache.org directory listing with an HTML-escaped ampersand in the URL:

{code}
%x(curl -L --stderr /dev/null 'https://archive.apache.org/dist/maven/maven-3/?F=0&V=1' | ...)
{code}

Because of "&", the V=1 (version sort) parameter is not applied. The listing is sorted lexicographically, so "tail -1" picks the wrong entry. For maven this resolves 3.9.9 instead of the latest 3.9.16:

{code}
$ curl -L --stderr /dev/null 'https://archive.apache.org/dist/maven/maven-3/?F=0&amp;V=1' | grep -o '<li>.*href="3.9.[0-9]*/"' | tail -1 | grep -o '3.9.[0-9]*'
3.9.9

$ curl -L --stderr /dev/null 'https://archive.apache.org/dist/maven/maven-3/?F=0&V=1' | grep -o '<li>.*href="3.9.[0-9]*/"' | tail -1 | grep -o '3.9.[0-9]*'
3.9.16
{code}

latest_ant_binary has the same bug and fails to pick up the latest 1.9.x.

Fix: replace "&amp;" with "&" in the listing URLs in latest_maven_binary.rb and latest_ant_binary.rb.
