[SOLVED] Compilation error only when "gradle build"

[Blackout]

Hello,

 

I have some issues with generics.

In eclipse (using JRE 7 with compilance setting set to 1.6), I have no error, my game launches well.

But when I try to make a release using "gradle build" command, I get a compilation error about generics.

 

\build\sources\main\java\fr\eyzox\dependencygraph\DependencyGraph.java:31: error: method buildIndex in class DataKeyProvider<K> cannot be applied to given types;
                        node.keyProvider.buildIndex(index, node);
                                        ^
  required: Map<KEY,DependencyGraph<KEY,? extends IData<KEY>>.Node>,DependencyGraph<KEY,? extends IData<KEY>>.Node
  found: Map<KEY,DependencyGraph<KEY,DATA>.Node>,DependencyGraph<KEY,DATA>.Node
  reason: actual argument Map<KEY,DependencyGraph<KEY,DATA>.Node> cannot be converted to Map<KEY,DependencyGraph<KEY,? extends IData<KEY>>.Node> by method invocation conversion
  where KEY,DATA,K are type-variables:
    KEY extends Object declared in class DependencyGraph
    DATA extends IData<KEY> declared in class DependencyGraph
    K extends Object declared in class DataKeyProvider

 

I don't know why it works in Eclipse but doesn't when build.

I've edit gradle.build to use Java 7 to compile with theses line :

sourceCompatibility = 1.7
targetCompatibility = 1.7

 

Source code is available here : https://github.com/RedRelay/FCH_DEBUG

 

Maybe it is pur java's generics missunderstanding, but I doubt it because all works fine in Eclipse.

 

Edit : This is for 1.9 atm so I use the recommended version of forge for MC 1.9 (1.9-12.16.1.1887)

Does this work in the dev environment?

[Blackout]

Yes it works on my dev environment 

[Animefan8888]

It seems the error is in your DependancyGraph on line 31.

[Blackout]

I saw, but there are no error on Eclipse and Eclipse build-in compilation works well.

I know at line 31, I call a method with generics parameters that seems not match for gradle but they match for Eclipse.

Thanks for helping me,

github repo is broken ? How can I fix it ? All works fine at home

[Blackout]

Oh ok my bad ^^

I use default build.gradle

The build.gradle in the repository is useless, I only use it to copy/paste when I update forge because I'm too lazy to edit version, group and archiveBaseName each time ^^ I should have remove it from git for a while ^^

 

All is default Forge 1.9-12.16.1.1887 configuration, and my .git is located in /src

 

I've gradle 2.7 installed on my computer so I don't need wrapper right ?

However, I copy/paste all file in mdk zip except gradlew.bat and gradlew.sh

I've always push only sources to git repo.

All other root files are set to default value.

 

I'll put the root directory on github after releasing if it's a better practice.

 

EDIT : I've done it for my others mods repo, I just wait releasing to rework this repo

If all fails just redownload the MDK and copy your files in.

[Blackout]

Already done, still the same error

I've create a new repo for debug purpose : https://github.com/RedRelay/FCH_DEBUG

I didn't know that Eclipse using its own compiler

I've worked on my java's generics understanding, and I've fixed the issue using

protected abstract <D extends IData<K>> void buildIndex(final Map<K, DependencyGraph<K, D>.Node> index, final DependencyGraph<K, D>.Node theNode) throws DuplicateKeyException;

instead of

protected abstract void buildIndex(final Map<K, DependencyGraph<K, ? extends IData<K>>.Node> index, final DependencyGraph<K, ? extends IData<K>>.Node theNode) throws DuplicateKeyException;

 

Thanks a lot

Of course Eclipse has its own compiler. How did you think the run button worked?
