Attempting to run this in an alpine-node Docker image (java is not installed).

Hey, have you found a fix / workaround for this one?

[joelnet]

I ended up creating a new Dockerfile with Java installed. You'll have do download the jdk from Oracle.

ENV JAVA_HOME /opt/java/current
ENV PATH $PATH:/opt/java/current/bin

COPY packages/jdk-8u212-linux-x64.tar.gz /opt/java/jdk-8u212-linux-x64.tar.gz

# Oracle Java - https://wiki.alpinelinux.org/wiki/Installing_Oracle_Java
RUN ( \
  cd /opt/java; \
  tar -zxvf jdk-8u212-linux-x64.tar.gz;\
  rm jdk-8u212-linux-x64.tar.gz; \
  chown -R root.root jdk1.8.0_212/; \
  ln -s jdk1.8.0_212 /opt/java/current; \
  printf "export JAVA_HOME=/opt/java/current\nexport PATH=$PATH:\$JAVA_HOME/bin\n" > /etc/profile.d/java.sh; \
  which paxctl || apk add paxctl; \
  cd ./current/bin; \
  paxctl -c java; \
  paxctl -m java; \
  paxctl -c javac; \
  paxctl -m javac; \
  )

It would be nice if Java wasn't needed though.

Hello,

I have the same issue on node:12-alpine in gitlab-ci pipeline.

I run in before_script to run once who failed every time just to install it:

 before_script:
    - apk --update add openjdk8-jre
    - npm run sonar || echo 'Sonar fail'
    - sed -i 's/use_embedded_jre=true/use_embedded_jre=false/g' /root/.sonar/native-sonar-scanner/sonar-scanner-4.4.0.2170-linux/bin/sonar-scanner

script:
    - npm run sonar

It works but it's very ugly.

Can you just put an args to set by le command line the boolean value of use_embedded_jre in sonar-scanner (sh & bat) script. To launch the cmd like this : npm run sonar -Duse_embedded_jre=false

Actually the value is hard coded :

set use_embedded_jre=true
if "%use_embedded_jre%" == "true" (
  set "JAVA_HOME=%SONAR_SCANNER_HOME%\jre"
)

if not "%JAVA_HOME%" == "" goto foundJavaHome

Thanks, Edo

Has there been any follow up on this? I am still having this issue on node alpine

Thank you, Edo (@epelaic), I have improved your sed a little bit:

set -- /root/.sonar/native-sonar-scanner/* && sed -i 's/use_embedded_jre=true/use_embedded_jre=false/g' "$1/bin/sonar-scanner"

Warning! Do not thinkless copy-paste, I'm not any good Shell-developer.

@bellingard the readme says:

sonarqube-scanner makes it very easy to trigger SonarQube / SonarCloud analyses on a JavaScript code base, without needing to install any specific tool or (Java) runtime.

It looks like this is not true, it does not work without a java runtime.

Ah ok: https://github.com/bellingard/sonar-scanner-npm/issues/59#issuecomment-463603165

The link in the comment above is dead, but i found this docker image that fixes the issue for alpine by installing glibc:

[gabssnake]

Hey @fabb, would like to contribute a small PR for the readme?

[gabssnake]

Hello again everyone,

Thanks for bringing this up. I created a list of potential improvements and mentioned this topic:
