lein droid build fails on "Hello world" sample project

[Frédéric Bourgine]

Hi,

I've created a new clojure android project using the following command:
lein new droid my-droid my.droid

I've modified my-droid/project.clj, just to indicate the android-sdk path and when I tried to build the project using: lein droid build the following error occurs:
error: package neko does not exist




In fact the compilation error arise when trying to java compile the SplashActivity.java generated by thelein-droid plugin.

Hereafter the SplashActivity.java file:

package my.droid;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.ImageView;
import android.widget.TextView;
import neko.App;

import my.droid.R;

public class SplashActivity extends Activity {

    private static boolean firstLaunch = true;

    @Override
    public void onCreate(Bundle bundle) {
        super.onCreate(bundle);

        if (firstLaunch) {
            firstLaunch = false;
            setupSplash();
            App.loadAsynchronously("my.droid.MainActivity",
                                   new Runnable() {
                                       @Override
                                       public void run() {
                                           proceed();
                                       }});
        } else {
            proceed();
        }
    }

    public void setupSplash() {
        setContentView(R.layout.splashscreen);

        TextView appNameView = (TextView)findViewById(R.id.splash_app_name);
        appNameView.setText(R.string.app_name);

        Animation rotation = AnimationUtils.loadAnimation(this, R.anim.splash_rotation);
        ImageView circleView = (ImageView)findViewById(R.id.splash_circles);
        circleView.startAnimation(rotation);
    }

    public void proceed() {
        startActivity(new Intent("my.droid.MAIN"));
        finish();
    }

}

The compilation error occurs at line 10 when trying to import neko.App class. However neko is included in project dependency.
Hereafter the project .clj file:

                             #"cljs-tooling\..+"]})

I sure I doing something wrong but I didn't find any way to fix it.

I am using the following leiningen version:
Leiningen 2.5.1 on Java 1.7.0_51 Java HotSpot(TM) 64-Bit Server VM

I've just tried to do the same, and it worked. I feel this might be Windows-related. You should run `DEBUG=1 lein droid doall` and post your build log.

Best regards,
Alex

Hi Alex,

Yes it seems related to Windows.

After setting `DEBUG=1`, I run `lein droid doall`.

Hereafter the log:

It might be related to recent changes in lein-droid with classpath construction. Please try changing lein-droid version to 0.4.1 and see if that helps.

Hi Alex,

Unfortunately, same compilation errors occur with 0.4.1 version.

[Frédéric Bourgine]

Hi Alex,

After some tests using lein droid on Windows, I probably found the reason of the compilation issue.

The neko.jar can not be resolved because my .m2 directory (i.e. the directory containing artefacts downloaded by leiningen) is located in a parent directory which name contains some characters with accent. 
When I try to do the same on an other account (which username doesn't contain accented characters), the compilation completes without any error.
