Pipeline Build fails due to Python not available error
Fix the Pipeline Build failure due to a Python error by creating a Maven project that uses the exec plugin to install Python3.
Description description
Environment
AEM as a Cloud Service
Issue/Symptoms
Python version 3.10 must be installed as the frontend code requires Python to build the application.
However, when deploying the pipeline in Cloud Manager, the build fails with the following error:
[ Exec Stream Pumper] [ INFO] npm ERR! gyp ERR! configure error

Resolution resolution
If Python is not installed, Maven can be installed by following these steps.
To create a Maven Project that uses the exec plugin to install Python3, a configuration to a pom.xml must be done.
Example:
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.example</groupId><artifactId>PythonInstaller</artifactId><version>1.0-SNAPSHOT</version><packaging>jar</packaging>
<build><plugins><plugin><groupId>org.codehaus.mojo</groupId><artifactId>exec-maven-plugin</artifactId><version>1.6.0</version><executions><execution><id>apt-get-update</id><phase>validate</phase><goals><goal>exec</goal></goals><configuration><executable>apt-get</executable><arguments><argument>update</argument></arguments></configuration></execution><execution><id>install-python3</id><phase>validate</phase><goals><goal>exec</goal></goals><configuration><executable>apt-get</executable><arguments><argument>install</argument><argument>-y</argument><argument>python3</argument></arguments></configuration></execution></executions></plugin></plugins></build></project>
The Maven configuration will run the apt-get update and apt-get install -y python3 commands during the validate phase of the Maven build lifecycle. Also, note that this will only work if the build is run in an environment where the apt-get command is available and running. The build needs to have sufficient permissions to install packages.
Similarly, if you need to install Python 3.11, the pom.xml should look like:
**```
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<build><plugins><plugin><groupId>org.codehaus.mojo</groupId><artifactId>exec-maven-plugin</artifactId><version>1.6.0</version><executions><execution><id>apt-get-update</id><phase>validate</phase><goals><goal>exec</goal></goals><configuration><executable>apt-get</executable><arguments><argument>update</argument></arguments></configuration></execution><execution><id>install-python3.11</id><phase>validate</phase><goals><goal>exec</goal></goals><configuration><executable>apt-get</executable><arguments><argument>install</argument><argument>-y</argument><argument>python3.11</argument></arguments></configuration></execution></executions></plugin></plugins></build></project>
```**
