Bitbucket pipeline docker image with jdk 1.8 , ant and wsgen

[yogesh_devi]

Hi Pipeline Experts 

I using  bitbucket pipeline to  build a legacy software that uses "wsgen" tool to build JAX-WS web services.

since the build is done using ant and  needs JDK 1.8 , I use an image called "frekele/ant:1.10.3-jdk8" 

However this image does not seem to have "wsgen" 

ANy suggestions on either if I can install a missing component ( like wsgen  in this case) or if I can switch to another image that has ant, jdk 1.8 and wsgen .  

Sincere thanks for your help

Hi 

I  started creating a docker image as suggested by Syahrul.

Just as a last ditch effort, I thought I will check if  wsgen does exist  on the frekele/ant:1.10.3-jdk8  image itself even though it does not run owing to possible issues with path. 

So I ran the frekele/ant:1.10.3-jdk8  docker container locally  and navigated through the links to java to lead me to the java  bin directory path .

I then looked for wsgen in that directory, and presto I found it in the java bindir. \

I am not sure why in the out of box container the path to java bindir is set  by default

Anyways if you like dirty details - this is how I navigated through links to java to get to java bindir 

# run docker image
docker run -it frekele/ant:1.10.3-jdk8 bash

# inside docker figure where is java located 
type java 
# points to /usr/bin/java
ls -l /usr/bin/java
# points to /etc/alternatives/java
ls -l /etc/alternatives/java
# points to /opt/java/bin/java; look for wsgen in the path /opt/java/bin
ls -l /opt/java/bin/wsgen
/opt/java/bin/wsgen -version
# wsgen version "2.2.9"

Thus having determined that java bin dir path was  /opt/java/bin and wsgen was in there I did couple of exports  in my script in my pipeline as follows 

export JAVA_HOME=/opt/java
export PATH=$PATH:$JAVA_HOME/bin

and I was good to go  

So the takeaway is - that if you want to dig into the docker image used for build - run the image locally and explore it so you know exactly what to do in your build 

Thanks all

G'day, @yogesh_devi 

It's best to create your own image using the "frekele/ant:1.10.3-jdk8" image as the base and installing the legacy software "wsgen" in it. Then, upload it to Docker Hub and use that image as your pipeline image. This way, you have your own customisable image when installed without relying on external email.

Hello Syahrul, 

Thanks a lot for your response - I was about to build a new image - however it occured to me that maybe wsgen exists on the "frekele/ant:1.10.3-jdk8" image and it simply isnt in the path .

So I looked for it and found it 

So basically my question is moot now .

I still sincerely appreciate your help
