Downgrading MacPorts: use Ant 1.8.4 to build Tomcat 6 in Yosemite 10.10.3

Building Tomcat6 on MacPorts fails on building jakarta-taglibs-standard-11 due to Maven 1.9.4 present in the MacPorts repo. The error manifests itself like this:

...
    [javac] /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_java_jakarta-taglibs-standard-11/jakarta-taglibs-standard-11/work/jakarta-taglibs-standard-1.1.2-src/standard/build.xml:178: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds

    [javac] Fatal Error: Unable to find package java.lang in classpath or bootclasspath

...

The build can be fixed by downgrading Ant:

cd ~
svn co -r 94758 http://svn.macports.org/repository/macports/trunk/dports/devel/apache-ant
cd apache-ant
sudo port install

Now tomcat can be installed from ports:

sudo port install tomcat6

Starting tomcat now shows we need some further customization:

# sudo port load tomcat6
# sudo less /opt/local/share/java/tomcat6/logs/catalina.err

That rings a bell. We need to run headless! To customize MacPort's Tomcat, edit setenv.local:

# sudo vi /opt/local/share/java/tomcat6/conf/setenv.local

This example is to use JDK1.7 and some self-signed certificate magic [setenv.local]

JAVA_JVM_VERSION=1.7
JAVA_OPTS="-Djava.awt.headless=true -XX:PermSize=500m -XX:MaxPermSize=800m -Xmx2g -Djavax.net.ssl.keyStore=/Users/doma/.keystore -Djavax.net.ssl.keyStorePassword=password -Djavax.net.ssl.trustStore=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/jre/lib/security/cacerts -Djavax.net.ssl.trustStorePassword=changeit"

Restart Tomcat6:

sudo port unload tomcat6
sudo port load tomcat6

Did we fix it?

Et voila. Tomcat started.

Background

The same process can be applied to downgrade anything in the ports tree. To find the proper release, see https://trac.macports.org/log/trunk/dports/devel/apache-ant

To see which versions you are currently having:

# sudo port installed apache-ant
The following ports are currently installed:
  apache-ant @1.8.4_0 (active)
  apache-ant @1.9.4_0

To use 1.9.4 again:

# sudo port activate apache-ant @1.9.4_0
--->  Deactivating apache-ant @1.8.4_0
--->  Cleaning apache-ant
--->  Activating apache-ant @1.9.4_0
--->  Cleaning apache-ant
# ant -version
Apache Ant(TM) version 1.9.4 compiled on April 29 2014
