Kay,
Yes you are right regarding the source file being in classpath ,I tried
with with the class file and below are the snippet of the exception i am
getting,
ARN : org.graylog2.rules.DroolsEngine - Unable to add rules due to
compilation errors.
org.graylog2.rules.RulesCompilationException: Message [id=1, level=ERROR,
path=r1.drl, line=1, column=0
text=Error importing : 'etc.code.PropertiesCache']
Message [id=2, level=ERROR, path=src/main/resources/null, line=17, column=0
text=Rule Compilation error Only a type can be imported.
etc.code.PropertiesCache resolves to a package]
Message [id=3, level=ERROR, path=src/main/resources/null, line=25, column=0
text=Rule Compilation error Only a type can be imported.
etc.code.PropertiesCache resolves to a package]
Message [id=4, level=ERROR, path=r1.drl, line=33, column=0
text=Rule Compilation error Only a type can be imported.
etc.code.PropertiesCache resolves to a package
PropertiesCache cannot be resolved]
Message [id=5, level=ERROR, path=*src/main/resources/null*, line=9, column=0
text=Rule Compilation error Only a type can be imported.
etc.code.PropertiesCache resolves to a package]
i am particularly interested in src/main/resources/null , does it mean my
class files needs to be in src/main/resources and a rebuild of graylog
source needs to be done for graylog to recognize my import. Kindly advice.
Attached detailed exception trace
