SnpEff ( http://snpeff.sourceforge.net/ )

"A program for annotating and predicting the effects of single nucleotide polymorphisms, SnpEff: SNPs in the genome of Drosophila melanogaster strain w1118; iso-2; iso-3.", Cingolani P, Platts A, Wang le L, Coon M, Nguyen T, Wang L, Land SJ, Lu X, Ruden DM. Fly (Austin). 2012 Apr-Jun;6(2):80-92. PMID: 22728672 [PubMed - in process]

This repository contains a tool_dependencies.xml file that downloads and installs SnpEff and SnpSift (SnpEff.jar and SnpSift.jar)

The install create an environment variable: SNPEFF_JAR_PATH that contains the path to the jar files.   Tools using this can generate a command line:
java -Xmx6G -jar \$SNPEFF_JAR_PATH/snpEff.jar eff -c \$SNPEFF_JAR_PATH/snpEff.config   ...

The snpEff.config file is also installed, which specifies the default location for installed SnpEff genome databases:
data_dir = ~/snpEff/data/

The location of a genome database can be set via the commandline option -dataDir.  

Another way to change the location of data_dir would be to create a symbolic link in the galaxy HOME directory:
ln -s genome_data_path/snpEff ~/snpEff
