TemplateSyntaxException: filter method not found about jinjava

[matthewrk]

Just realised that I was running a slightly old version of Jinjava, updated to 2.1.11 and unfortunately still having the same issue.

@matthewrk, this sounds like the same issue you're having. #39

[matthewrk]

@boulter thanks!, it seems that it is indeed related but I can't seem to find what the conflict is.

I started a blank project with the test case from #39 and sure enough it worked, so then I copied in my dependencies for Spring Boot and it produced the error that I described above.

This is my maven file for my simple test project:

And this is the dependency tree (just from mvn dependency:tree):

In that state it errors with:

[TemplateError{severity=FATAL, reason=SYNTAX_ERROR, message=TemplateSyntaxException: Method not found: class com.hubspot.jinjava.lib.filter.UpperFilter.filter(java.lang.String, com.hubspot.jinjava.interpret.JinjavaInterpreter), fieldName=null, lineno=1}]
08:41:04.718 [main] DEBUG jinjava - hello {{ testvar | upper }}

But by simply moving the JinJava dependency to the top of the dependencies list, it works. That is true of both my simple test project and my main project where I originally experienced the issue. So it seems to be a conflict somewhere, I just don't know where! I can't see any shared libraries in the dependency tree.

My guess is it's this line:

[INFO] | | +- org.apache.tomcat.embed:tomcat-embed-el:jar:8.0.36:compile

try excluding that.

[matthewrk]

@boulter yep that did the trick, along with org.glassfish.javax.el:3.0.0 which comes from undertow on my main project.

I'm fairly new to Java so sorry if this is a stupid question, but these are all EL packages, which a bit of googling tells me are "Expression Language" packages. Are they all alternate implementations of the same interface? Having a hard time gauging the significance of these excludes and what exactly is happening here. Thanks for your help so far.

[boulter]

Here's some background on Java's EL. https://en.wikipedia.org/wiki/Unified_Expression_Language. Tomcat includes an implementation of EL 3.0 whereas Jinjava uses JUEL's 2.0 implementation.
