<!-- If this is a particularly complex change or feature addition, you
can request a dedicated Nx release for this pull request branch. Mention
someone from the Nx team or the `@nrwl/nx-pipelines-reviewers` and they
will confirm if the PR warrants its own release for testing purposes,
and generate it for you if appropriate. -->

## Current Behavior
<!-- This is the behavior we have today -->
got this error:
```
 NX   Cannot read properties of undefined (reading '1')

TypeError: Cannot read properties of undefined (reading '1')
    at fileDataDepTarget (/Users/emily/code/tmp/spring-boot/.nx/installation/node_modules/nx/src/config/project-graph.js:13:18)
    at ProjectGraphBuilder.calculateTargetDepsFromFiles (/Users/emily/code/tmp/spring-boot/.nx/installation/node_modules/nx/src/project-graph/project-graph-builder.js:271:74)
```

this happens because the project in the dependency file is in format
like `:spring-boot-project:spring-boot-autoconfigure (*)`. need to take
out the text after space.

## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->

<!-- Please link the issue being fixed so it gets closed when this is
merged. -->
