Gradle build fails in jenkins:alpine container: UnsatisfiedLinkError: linux-amd64/libnative-platform.so: libstdc++.so.6:

Recently I started using Jenkins in a Docker container with Oracle Java 8. When building a project with Gradle I get this error message:

UnsatisfiedLinkError: linux-amd64/libnative-platform.so: libstdc++.so.6: cannot open shared object file: No such file or directory

In Jenkins I selected "Force GRADLE_USER_HOME to use workspace" with no luck at all. The file libnative-platform.so is in the directory expected but gradle won't work. I tried installing Gradle in the container and same result. My last setup is with Gradle Wrapper.

I looked everywhere but I had no luck on my quest. I appreciate if someone can shed a light on this.

You can make this work by installing the libstdc++ package in Alpine

apk add --no-cache libstdc++

libstdc++.so.6: cannot open shared object file

libnative-platform.so of the JRE/JDK is linked against gnu libc but Alpine images are based on musl libc.

The easy solution is to use a glibc based docker image like Debian, if you want to stick with Alpine you might find some clues in this github issue.

The problem is that Oracle JDK is linked against GNU C library (glibc) that is not available here.

Alpine Linux doesn’t use glibc as conventional distributions like Debian, Fedora or Gentoo. Instead, it uses musl libc, a lightweight, fast, simple and standards-conform C library (i.e. everything that glibc is not).

The solution is very simple, just install OpenJDK from the Alpine repository (package openjdk8). Don’t worry about compatibility, Oracle JDK 8 is just branded distribution of OpenJDK 8, the code base is nearly identical.

If you insist on Oracle JDK for whatever reason and don’t care about security at all*, then don’t use Alpine Linux, but some conventional distribution…

You can read more in my article JRuby on Alpine Linux on the JRuby wiki.

* Oracle JDK has restricted cryptography by default, because of U.S. policy. It’s distributed with Ask.com adware. And because it’s distributed only as a BLOB, you can’t know what else bad is inside…
