How to correct Tycho generics compile error -- JDT compile gives no error

Discussion:

(too old to reply)

First time Tycho user (using Eclipse Mars.2), converting a plugin
project to use Tycho to do the build.

Problem is that the Maven Build is throwing a compiler error, where the
JDT compiler shows no error.

Tried to ensure that the build would use the JDT, but still getting the
same error.

What am I missing?

Thanks ...

Tycho 0.24.0 is using the JDT compiler version from Mars.1 [1]

To verify this is not a JDT bug, you could

- use an eclipse Mars.1 IDE and check if compilation using the IDE works fine
- if it consistently fails with Mars.1, try using a newer version of org.eclipse.jdt.core, see e.g.

https://git.eclipse.org/c/platform/eclipse.platform.releng.aggregator.git/tree/eclipse-platform-parent/pom.xml#n459

also, mvn -X will give you the compilation classpath, so you could check if there is anything different.

For reference, [2] are the fixes for the JDT compiler done for Mars.2. On first glance there are some fixes related to generics, so looks like it's possible this is/was a JDT bug.

Jan

FWIW

I have only two instances of Eclipse installed: Mars.1 from the standard
downloaded zip; and Mars.2 installed using the MSI installer, with its
plugins installed into a .p2/pool entirely separate from Mars.1.

For both Mars.1 and Mars.2, the Java(JDT) editor reports no errors - I
can find no preference setting to adjust, let alone turn off this type
of error. The standard Eclipse IDE export plugin works and the plugin
works without error.

The console output from running mvn -X is at
https://www.dropbox.com/s/f7yeff1yeyj2910/CompileOutput.txt?dl=0
I could see nothing that would indicate it using a wrong
compiler/setting, but I am still very new to Maven/Tycho.

The Java source file in question is just a local copy of Eclipse's own
/org.eclipse.jdt.internal.ui.preferences.CodeAssistAdvancedConfigurationBlock/

Casting is a short-term solution. I will try to prep a sample project
to demo the problem.

Thanks.

Found it. The parent POM contained a reference to the Luna P2 repo. My
bad for failing to see it earlier.

Could it be that you are using an older version of
"org.eclipse.core.runtime" during the build time with Tycho? This would
explain the issue.

I think you target platform is referring to an older version of
getAdapter() that does not use generics so a type cast is missing

Jeff

Post by Jens Reimann
Could it be that you are using an older version of
"org.eclipse.core.runtime" during the build time with Tycho? This would
explain the issue.
First time Tycho user (using Eclipse Mars.2), converting a plugin project
to use Tycho to do the build.
Problem is that the Maven Build is throwing a compiler error, where the
JDT compiler shows no error.
Tried to ensure that the build would use the JDT, but still getting the
same error.
What am I missing?
Thanks ...

"Legacy code" often differs from its suggested alternative by actually
