I'm working on a project where I need to run the maven install command in other projects. To resolve this, I used MavenCli which allows the execution of Maven commands by a Java Spring Boot project. A snippet of the executed code:

private int install(File pom, PrintStream out) throws IOException {
        log.info("Maven install started: " + pom.getCanonicalPath());
        System.setProperty("maven.multiModuleProjectDirectory", pom.getCanonicalPath());
        return this.maven.doMain(new String[]{
                        "install"},
                pom.getCanonicalPath(), out, out);
    }

The this.maven is initialized in the constructor with this.maven = new MavenCli(). The pom file have the path: "./src/main/resources/github-tasks/main/java-coding-tasks".

In localhost, the code works perfect, but when I deploy in Heroku and call this method, Heroku throw a NoSuchElementException:

I already tried to change the pom file to relativePath, absolutePath, "./src/main/resources/github-tasks/main/java-coding-tasks/pom.xml", mixed the paths( in the system property "maven.multiModuleProjectDirectory" used relativePath and in the maven.doMain used absolutePath and vice versa), etc.

By the way, if I try to list the files in the directory that gives the NoSuchElementException, the files are there:

log.info("Directory in maven install: {}", Arrays.toString(pom.list()));

Log:

Directory in maven install: [pom.xml, .github, src, .git, README.md, .gitignore]

Does anyone know what's causing this and how to fix it?
