Travis CI doesn't deploy to Azure from GitHub the war file correctly

My problem is that the packaged war file is not deployed from GitHub to Azure using Travis-CI correctly - the entire repository with the generated files are just copy-pasted. Here is what I do:

My approach:

I follow the Travis tutorial about Azure web app deployment and try to achieve the same in the minimal form. My goal is to assemble a war file and deploy it to Azure web app with Tomcat 8.0 container.

My project has the following .travis.yml configuration (I have omitted Java-8 definition, Sonar add-ons, and Coveralls after_success script for the sake of brevity):

script:
   - mvn clean org.jacoco:jacoco-maven-plugin:prepare-agent package sonar:sonar

deploy:
   provider: azure_web_apps
   skip_cleanup: true

I use AZURE_WA_USERNAME, AZURE_WA_PASSWORD and AZURE_WA_SITE environment variables.

I follow the standard Maven directory structure. The output directory is the standard /target. Thus, on the Travis is generated into:

/home/travis/build/MY_USERNAME/MY_WEBAPP/target/MY_WEBAPP.war

Where MY_USERNAME is the GitHub login name and MY_WEBAPP is the name of my application. The deployment looks fine at the first sight (I skipped similar lines):

Done. Your build exited with 0.

What is wrong and how it should be correct:

If I upload manually the war file via FTP(S) to the Azure directory /site/wwwroot/webapps, it's unpacked and deployed within a minute and works well.

Unlike the manual copy, Travis takes all the content and copy-paste it literally into the Azure webapp resulting in the mess like:

Azure directory structure

The war file hasn't been uploaded into the webapps folder. The newly created Azure webapp contains site/wwwroot/webapps/ROOT folder and is needed to upload the war file on the ROOT folder level. I have expected Travis would perform "smarter" behavior.

Question:

How to deploy to Azure from GitHub using Travis-CI correctly? I bet I miss something that isn't documented.

My workaround-attempts:

I have tried to fix the thing in several ways (none of them has worked). I consider all of them dirty:

  1. I tried to specify what to deploy in .travis.yml (no effect, everything is copied still):

    file_glob: true
file: "/home/travis/build/MY_USERNAME/MY_WEBAPP/target/MY_WEBAPP*.war"

  2. An ugly bruteforce: Change the output directory from /target to /webapp resultin to override the destination folder in Azure upon deployment in the <build> section of 'pom.xml`:

    <directory>/webapps</directory>
...
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <configuration>
        <warName>MY_WEBAPP</warName>
        <outputDirectory>/webapps</outputDirectory>
    </configuration>
</plugin>

  3. Rename the output folder to webapps in .travis.yml:

    after_success:
 - bash mv /home/travis/build/MY_USERNAME/MY_WEBAPP/target/ /home/travis/build/MY_USERNAME/MY_WEBAPP/webapps/

    /bin/mv: /bin/mv: cannot execute binary file

Solution

  • I have resolved the issue with uploading deployment scripts:

    .deployment

    [config]
command=deployment.cmd

    deployment.cmd

    @echo off
echo Azure: Deploying site

echo Azure: Removing the current war file
del %DEPLOYMENT_TARGET%\webapps\MY_WEBAPP.war /S /Q

echo Azure: Removing the current webapp folder
rmdir %DEPLOYMENT_TARGET%\webapps\MY_WEBAPP /S /Q

echo Azure: Copying war to the webapps folder
xcopy %DEPLOYMENT_TARGET%\..\repository\target\MY_WEBAPP.war %DEPLOYMENT_TARGET%\webapps /Y /s
