Unable to build latest weasis source code

[Meer Asgar Hussain Bahawdeen]

Hi all,

After building the latest Weasis source code, while building the native binaries and installers, getting the following error.

$ ./build/script/package-weasis.sh --jdk "/usr/lib/jvm/jdk-25.0.3+9"
rootdir: /home/demo/Weasis_466/weasis-native
Error: Could not find or load main class org.weasis.core.util.NativeLibrary
Caused by: java.lang.ClassNotFoundException: org.weasis.core.util.NativeLibrary

ERROR: Cannot get Java system architecture

I tried in Linux and Windows with both Git Bash and Cygwin, getting the same error.

Please assist me on this.

Could someone please assist me on this issue?

Install OpenJDK 17

Ubuntu/Debian:

sudo apt update
sudo apt install openjdk-17-jdk -y

Check:

java -version

Should show something like:

openjdk version "17"

---

Then rebuild project first:

cd /home/demo/Weasis_466
./mvnw clean install

OR if using Gradle:

./gradlew build

After successful build:

cd weasis-native
./build/script/package-weasis.sh --jdk "/usr/lib/jvm/java-17-openjdk-amd64"

---

Also verify the class exists:

find . -name "*.jar" | xargs jar tf | grep NativeLibrary

If nothing appears, the project did not compile correctly.

  Many Java projects including Weasis do NOT yet fully support Java 25.

Hi,

I tried in Open JDK 17 and the same issue occurred,

$ ./build/script/package-weasis.sh --jdk "/usr/lib/jvm/java-17-openjdk-amd64"
rootdir: /home/demo/weasis-native

Error: Could not find or load main class org.weasis.core.util.NativeLibrary

Thanks in advance.
