Micro Integrator 4.2.0 maven build - error - Invalid CEN header

Question

I am new to ws02, I am trying to build ws02 micro integrator from Ubuntu 22.04 terminal + Maven 3.6.3 + JDK 17.0.10+7. I am facing problems, getting error "Invalid CEN header" during the compilation. I explain all steps I did.

1. Downloaded JAVA JDK 17.0.10+7 OpenJDK17U-jdk_x64_linux_hotspot_17.0.10_7.tar

   from https://adoptium.net/en-GB/temurin/releases/?os=linux&arch=x64&package=jdk&version=17

2. Set JAVA HOME path in .bashrc

   jammy@Tasconnect-016:~$ echo $JAVA_HOME

   /opt/jdk-17.0.10+7

3. Verified Java version

   jammy@Tasconnect-016:~$ java --version

   openjdk 17.0.10 2024-01-16

   OpenJDK Runtime Environment Temurin-17.0.10+7 (build 17.0.10+7)

   OpenJDK 64-Bit Server VM Temurin-17.0.10+7 (build 17.0.10+7, mixed mode, sharing)

4. Verified maven version 3.6.3

   jammy@Tasconnect-016:/$ mvn --version

   Apache Maven 3.6.3

   Maven home: /usr/share/maven

   Java version: 11.0.18, vendor: Eclipse Adoptium, runtime: /opt/jdk-11.0.18+10

5. Cloned the repo from https://github.com/wso2/micro-integrator

   jammy@Tasconnect-016:~/mi$ git clone https://github.com/wso2/micro-integrator.git

6. List branches for mi 4.2.0 version

   jammy@Tasconnect-016:~/mi/micro-integrator$ git branch -r | grep "4.2.0"
     origin/master-4.2.0
     origin/release-4.2.0-alpha-l895
     origin/release-4.2.0-d731
     origin/release-4.2.0-m1-p301
   
   

   7 . Checked out branch "origin/release-4.2.0-d731" - assuming this is the release version branch for MI 4.2.0

   jammy@Tasconnect-016:~/mi/micro-integrator$ git checkout origin/release-4.2.0-d731
   

   8. Gave command , wanted to skip jacoco tests

 mvn clean package -Dskip.jacoco.check=true

9 . Got below error " Invalid CEN header " at

[ERROR] Failed to execute goal org.apache.felix:maven-bundle-plugin:3.3.0:bundle (default-bundle) on project org.wso2.micro.integrator.initializer: Error calculating classpath for project MavenProject: org.wso2.ei:org.wso2.micro.integrator.initializer:4.2.0 @ /home/jammy/mi/micro-integrator/components/org.wso2.micro.integrator.initializer/pom.xml: The JAR/ZIP file (/home/jammy/mi/micro-integrator/components/mediation/inbound-endpoints/org.wso2.micro.integrator.inbound.endpoint/target/org.wso2.micro.integrator.inbound.endpoint-4.2.0.jar) seems corrupted, error: Invalid CEN header (invalid extra data field size for tag: 0xbfef at 242516) -> [Help 1]

So search for this org.wso2.micro.integrator.inbound.endpoint-4.2.0.jar file inside ~/.m2/repository . But found no such file .

But I found the file inside ~/mi/micro-integrator/components/mediation/inbound-endpoints/org.wso2.micro.integrator.inbound.endpoint/target .

Deleted it rm -f org.wso2.micro.integrator.inbound.endpoint-4.2.0.jar . Rebuild with "mvn package -Dskip.jacoco.check=true" again same error .

Now again I went back to ~/.m2 folder and I searched for all files with string "inbound.endpoint". Found 3 entries with suffix *-4.7.175.jar" not exactly "4.2.0.jar"

grep: ./org/wso2/carbon/mediation/org.wso2.carbon.inbound.endpoint.persistence/4.7.175/org.wso2.carbon.inbound.endpoint.persistence-4.7.175.jar: binary file matches

grep: ./org/wso2/carbon/mediation/org.wso2.carbon.inbound.endpoint.osgi/4.7.175/org.wso2.carbon.inbound.endpoint.osgi-4.7.175.jar: binary file matches

grep: ./org/wso2/carbon/mediation/org.wso2.carbon.inbound.endpoint/4.7.175/org.wso2.carbon.inbound.endpoint-4.7.175.jar: binary file matches

Deleted these 3 files

Re-ran the command mvn package -Dskip.jacoco.check=true ( without clean because I did not want to rebuild all previously built JARs) . But again same error thrown "Invalid CEN .

How can I fix this problem?

Answer 1

The following is from the README of the source repo. Hence try downgrading to JDK 11.

Please note that the product can be build using only JDK 11 but the integration tests can be run in either JDK 11 or 17.
