# Troubleshooting

## Error: "Project with path ':RobotCore' not found"

**Symptom:**
```
FAILURE: Build failed with an exception.
* What went wrong:
Project with path ':RobotCore' not found in build ':ftc-sdk'.
```

**Cause:** FTC SDK was not cloned or is at wrong location.

**Solution:**

1. Check if SDK exists:
```bash
ls ~/ftc-sdk
# Should show: FtcRobotController, RobotCore, Hardware, etc.
```

2. If SDK doesn't exist, clone it:
```bash
git clone --depth 1 --branch v10.1.1 \
    https://github.com/FIRST-Tech-Challenge/FtcRobotController.git \
    ~/ftc-sdk
```

3. Check your project's `gradle.properties`:
```bash
cat gradle.properties
# Should show: ftcSdkDir=/home/yourusername/ftc-sdk
```

4. Update if path is wrong:
```bash
echo "ftcSdkDir=$HOME/ftc-sdk" > gradle.properties
```

5. Try again:
```bash
./gradlew test
```

## Error: Can't find SDK at specified path

**Solution:** Set environment variable:
```bash
export FTC_SDK_DIR=~/ftc-sdk
./gradlew test
```

Or edit `gradle.properties` in your project.

## SDK exists but wrong version

**Solution:** Update SDK to correct version:
```bash
cd ~/ftc-sdk
git fetch --tags
git checkout v10.1.1  # or whatever version you need
```

## Fresh Start

If all else fails:

```bash
# Remove old SDK
rm -rf ~/ftc-sdk

# Remove old project
rm -rf my-project

# Start fresh
ftc-new-project my-project

# Verify SDK was cloned
ls ~/ftc-sdk

# Test
cd my-project
./gradlew test
```

## Verify Setup

Run this diagnostic:

```bash
#!/bin/bash
echo "=== FTC Setup Diagnostic ==="
echo ""
echo "1. SDK Directory:"
ls -la ~/ftc-sdk 2>/dev/null || echo "  ✗ SDK not found at ~/ftc-sdk"
echo ""
echo "2. SDK Modules:"
ls ~/ftc-sdk/RobotCore 2>/dev/null && echo "  ✓ RobotCore found" || echo "  ✗ RobotCore missing"
ls ~/ftc-sdk/Hardware 2>/dev/null && echo "  ✓ Hardware found" || echo "  ✗ Hardware missing"
echo ""
echo "3. Project gradle.properties:"
cat gradle.properties 2>/dev/null || echo "  ✗ No gradle.properties in current dir"
echo ""
echo "4. Environment:"
echo "  FTC_SDK_DIR=$FTC_SDK_DIR"
```

Save as `check-setup.sh` and run it in your project directory.
