JDK 1.5 java.lang.Enum Buid Failure using Maven 2.0.8
I am using JDK 1.5 / Maven 2.0.8 and am attempting mvn clean install on a simple project that contains the following snippet:
...
public final Class<? extends Enum<? extends IDTOPhase>> getDTOPhaseLifeCycleStrategy(){
return someEnumClass;
}
...
for(java.lang.Enum<? extends IDTOPhase> phase : getDTOPhaseLifeCycleStrategy().getEnumConstants()){
...
}
...
The problem is that this compiles w/o a problem using ANT (or Eclipse build), but fails using Maven. I get the error:
... incompatible types
found : java.lang.Enum<? extends IDTOPhase>
required : java.lang.Enum<? extends IDTOPhase>
I even set the maven-compiler-plugin to ensure compilation in 1.5
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.0.2</version>
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>
</plugin>
Any clue??? Thanks!

To verify this you should try switching Eclipse to use your installed JDK
compiler instead of the built in one.
William also mentioned that ANT was producing successful builds as well, so
unless ANT also uses it's own compiler it might be another issue..

I played with your sample a bit and wrote a lengthy response in JIRA.
I am reasonably convinced this is simply an example where Eclipse's
JDT compiler is doing "something extra" that allows your code to work,
but it really doesn't. You can't always trust Eclipse, as it does not
dispatch to your system's JDK for compiling like Maven does (as far as
I understand what is happening under the hood in Eclipse and Maven).

RES: JDK 1.5 java.lang.Enum Buid Failure using Maven 2.0.8
Posted by Arthur Rodrigues Stilben <ar...@extendnet.com.br>.
I would like to know how can I do to use two kinds of packages in the same file. For example, I have an app.class and I want to create an app.jar and an app.war file. How can I do that?

Zip up a small sample project, create a JIRA issue, and attach it.
Then someone can look at your issue more closely.
