Wildfly 10.1 build fails with compilation errors in Weld Subsystem

[eduarddedu]

Benevolent reader,

I have synced the master branch in my local WildFly repository with the upstream master branch.

Now HEAD is at commit f9e868**** - Merge pull request #9419 from gytis/master-WFLY-7514.

Next I tried to build WildFly with:

           mvn clean install -e -DskipTests

The build fails. It looks  like a number of methods are invoked with arguments that do not match the expected parameters:

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.5.1:compile (default-compile) on project wildfly-weld: Compilation failure: Compilation failure:

[ERROR] ****/wildfly/weld/subsystem/src/main/java/org/jboss/as/weld/deployment/BeanDeploymentArchiveImpl.java:[99,33] method add in interface org.jboss.weld.bootstrap.api.ServiceRegistry cannot be applied to given types;

[ERROR] reason: inference variable S has incompatible bounds

[ERROR] equality constraints: capture#1 of ? extends org.jboss.weld.bootstrap.api.Service

I'm using Java 1.8 and Maven 3.3.9 on a MacBook running OSX El Capitan (10.11.6). I also have an active jboss-developer-repository profile defined in the global maven settings.xml config.

My question is, should I submit a report about this problem in the WildFly issue tracker? It looks like a major thing.

PS: Sorry for the newbie question, just want to make sure I'm not missing something here.

Update your java 8 to later update.

you are probably using jdk8 with < u45

btw, latest jdk8 update is 112

Hi Tomaz,

Thanks for the reply.

I have updated the JDK, now java -version outputs:

java version "1.8.0_112"

Java(TM) SE Runtime Environment (build 1.8.0_112-b16)

Java HotSpot(TM) 64-Bit Server VM (build 25.112-b16, mixed mode)

Just to be sure, I checked javac version also and it is:

javac 1.8.0_112

I tried to rebuild WildFly with:

     mvn clean install  -DskipTests

The build failed with the same error.

Hi,

I just updated my JDK to the same you have and Weld subsystem does compile without any problems in 10.x branch as well as in master branch. It's highly unlikely that there is stuff in official WIldFly git which wouldn't compile. So the problem must be somewhere else. Are you sure you don't have any local changes?

Hi Tomas,

It turns out Maven was using the 1.8.0_05 jdk, because that’s what the JAVA_HOME variable was pointing to.

I set JAVA_HOME to the location of the new jdk, I trust the build will now succeed.

Thanks for your help!
