CAT EOF generated in a single line fail to run

Question

I have a yaml file where I want to write a XML:

  script:
    - >
      cat > settings.xml << EOF
      <?xml version="1.0" encoding="UTF-8"?>
      <settings xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd" xmlns="http://maven.apache.org/SETTINGS/1.1.0"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <servers>
      <server>
      <username>$USERNAME</username>
      <password>$PASSWORD</password>
      <id>central</id>
      </server>      
      </servers>
      </settings>
      EOF

If I run the cat command in my terminal, it works but when it's executed by my pipeline, this command become a single line failing:

cat > settings.xml << EOF <?xml version="1.0" encoding="UTF-8"?> <settings xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd" xmlns="http://maven.apache.org/SETTINGS/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <servers> <server> <username>$USER</username> <password>$PASSWORD</password> <id>central</id> </server> </servers> </settings> EOF

With the error:

parse error near `<'

Any idea how to fix this error or generate a well formated XML?

There are two problems:

Incorrect syntax (incorrect cat > settings.xml << EOF instead of correct cat << EOF > settings.xml)
The end-string EOF must be at the beginning of the line but it isn't.

To run this from the command line:

Type cat << EOF > settings.xml and press ENTER.
Paste (or type by hand) your XML document (without the end-string EOF) and press ENTER.
Type EOF (make sure it is at the beginning of the line!) and press ENTER.

You will be presented with the command prompt. Type ls -l settings.xml to see the newly created file.

To run this from a script:

Open your text editor and follow the steps 1, 2 and 3.

Save it under the name, lets say script.sh and make it executable:

chmod 755 script.sh

Run it:

./script.sh

When the command promt is back, type ls -l settings.xml, to see the newly created file.
