Eclipse で作成された、1 つのアクティビティを持つサンプル Android アプリがあります。このコマンドを実行して、このプロジェクトの ant ビルド ファイルをビルドしました。

android create project --target 8 --name SampleApp --path ./SampleApp --activity MainActivity --package com.example.sampleapp

「ant debug」を実行すると、プロジェクトが正常にビルドされ、apk ファイルが作成されます。

-post-build:

debug:

BUILD SUCCESSFUL
Total time: 1 second

次に、Android テスト プロジェクトを作成します。次のコマンドを実行します。

android create test-project -m ../SampleApp -n SampleAppTest -p SampleAppTest

これにより、ビルド ファイルを含む SampleAppTest ディレクトリが正常に作成されました。src/com/example/sampleapp/MainActivityTest.java という 1 つのクラスがあります。

package com.example.sampleapp;

import android.test.ActivityInstrumentationTestCase2;

public class MainActivityTest extends ActivityInstrumentationTestCase2<MainActivity> {

    public MainActivityTest() {
        super("com.example.sampleapp", MainActivity.class);
    }

}

このプロジェクトを構築したい。http://developer.android.com/tools/testing/testing_otheride.html#RunTestsAntにあるチュートリアルでは、「ant run-tests」を実行できるはずだと書かれています。残念ながら、このターゲットは存在しません:

$ ant run-tests
Buildfile: /Users/cmuraru/Work/androidtest/SampleAppTest/build.xml

BUILD FAILED
Target "run-tests" does not exist in the project "SampleAppTest". 

Total time: 0 seconds

「ant デバッグ」を試みると、コンパイル時に (SampleApp からの) MainActivity クラスが見つからないというエラーが表示されます。

ここで何が欠けている/間違っていますか? どんな助けでも大歓迎です。

Okay, I spotted the problem. I failed to mention that in ant.properties, I've changed the out.dir location to "../build". Because of this, the compiler did not know where to get the class files of the SampleApp when building the SampleAppTest. So one solution is to delete the out.dir entry in ant.properties, but I did not want that. I had to find a way to tell the compiler where to get these classes. The solutions I found was to override the "-compile" target in build.xml like so:

<property name="SampleApp.build.location" value="../build"/>
    <target name="-compile" depends="-build-setup, -pre-build, -code-gen, -pre-compile">
        <do-only-if-manifest-hasCode elseText="hasCode = false. Skipping...">
            <!-- merge the project's own classpath and the tested project's classpath -->

                <path refid="tested.project.classpath" />
            </path>
