I am trying to run the maven-embedder from a plugin's Mojo that I develop.

I am using the mavenCli like below,

 

```java
MavenCli cli = new MavenCli();
cli.doMain(new String[] {"clean","compile"}, project.getBasedir().getAbsolutePath(), System.out, System.err);
```

 

Here are the dependencies in my pom.xml

 

 

```java

org.apache.maven
maven-embedder
3.9.8
provided

org.apache.maven
maven-compat
3.9.8
provided

org.eclipse.sisu
org.eclipse.sisu.plexus
0.3.5
provided

org.eclipse.sisu
org.eclipse.sisu.inject
0.3.5
provided

```

The full source code of the plugin can be found here:

https://github.com/HomeOfTheWizard/spring-bridge-maven-plugin/tree/feature/embedder-for-compilation

 

When using this plugin in another maven plugin project,

I have the following error.

```java
[INFO] [ERROR] Error executing Maven.
[INFO] [ERROR] Unable to create injector, see the following errors:

**Affects:** 3.9.8

Start with the plugin source linked in the issue and reproduce the MavenCli invocation from another plugin Mojo using Maven 3.9.8. Read the injector failure around SessionScoped and ReactorReader, then trace the provided maven-embedder, maven-compat, and Sisu dependencies. Done means the embedded clean compile runs without the injector error.
