Here's my error.
Buildfile: build.xml
error_analysis:
BUILD FAILED
file:C:/cagn/WEB-INF/examples/BatchExample/build.xml:23:
java.lang.NumberFormatE
xception: ${ea_survivalVar}
I tried adding dependencies, but it didn't help, plus the property is
currently set in the same target as it is used, it seems it should be
available.
