Maven appears to be ignoring source and target in webapp - java

I'm getting "Generated servlet error:|try-with-resources is not supported in -source 1.5". 1.5 is maven's default according to another question on the topic, but I thought I had fixed that in my pom.xml -
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"

Ultimately, I think the question is probably "what have I done wrong that maven is ignoring the source and target specifications?" There are similar questions out there, but the ones I've seen are either not solved or suggest things that exist in my pom.
Any help would be appreciated.


Jetty is using 1.5 source and target args by default for JSP compilation. See Jetty embedded and JSP compilation to 1.7? for pointers and info on switching Jetty to use 1.7

Error with Spark: NoSuchMethodError: scala.Predef$.$conforms()Lscala/Predef$$less$colon$less

I've got an application which streams Twitter posts.
It worked correctly, but after modifying the build path, I didn't manage to set it how it was before. I keep getting this error:

I already read all of the similar questions, but none of them helped me, because I tried to import the right versions of the jars, but it still doesn't work.
How can I fix this?

Looks like you are trying to use a kafka library compiled in Scala 2.10 in a Spark cluster compiled in other version (probably 2.11). Try this change in your pom.xml:

Maven cycle dependency

I'm new to Maven and Im trying to make my own Java EE Maven project with some frameworks...
I have started with two modules and one parent module.
The problem is that Im getting this error when Im issue mvn clean:

and
Missing artifact org.tepo:Jporto-ejb:ejb:0.0.1-SNAPSHOT:compile on web module...
Thank you for your help!

Your parent pom depends on your modules which depend on your parent pom.
What you could have done is add to your parent pom
<modules>
<module>module1</module>
<module>module2</module>
</module>
Your modules have to be subdirectories with the names you give them.
