Error when build Ella, "java.lang.RuntimeException: The executable 'android' is not in the path"

[SioYooo]

Hi there,

I have tried to built the ella for a few days, however it seems like it is not working. My error is the same as the other issue page:
(#12)

I have tried to build Ella on my Mac and also on a ubuntu server which is running 20.04.

I have installed all the requested environment.

And then I run the ant command on the ella directory, it shows this error message:

ant
Buildfile: /Users/sioyoo/tools/ella/build.xml

create-keystore:

build:

compile:

jar:

However I have set the path for Android.jar and also the android build tool in the ella.settings file

#Copy this file to a file named "ella.settings"
# and change that file if necessary

# set to "true" if the instrumented app will be executed on an emulator *AND*
# the ella server will be run on the host machine of the emulator.
# otherwise set to "false"
ella.use.emulator.host.loopback=true

# if ella.use.emulator.host.loopback is set to "false" *AND*
# ella server will be running on a machine that is different
# from the machine on which instrumentor is run, then set
# the following to the IP address of the machine on which
# the ella server will be run
#ella.server.ip=1.2.3.4

#port number that ella server is listening on
ella.server.port=23745

# directory where ella stores coverage data and other stuff
ella.outdir=ella-out

ella.instrumentor=com.apposcopy.ella.MethodCoverageInstrumentor
#ella.instrumentor=com.apposcopy.ella.CallArgInstrumentor,com.apposcopy.ella.MethodParamInstrumentor

# generate a trace that can be fed to traceview toold
ella.android.debug=false

# file that list names of classes that are excluded from instrumentation
ella.exclude=ella-exclude.txt

# max heap space given to JVM running the instrumentor 
ella.instrumentor.max.heapsize=2g

# max heap space given to JVM running the server
ella.server.max.heapsize=2g

# path to "build-tools" inside android SDK
# in default setting, the path is estimated
#ella.android.buildtools.dir=/opt/android-sdk-linux/build-tools/22.0.1/

# android jar to compile (ella runtime library) against
# in default setting, the path is estimated
#ella.android.jar=/opt/android-sdk-linux/platforms/android-19/android.jar

# settings used by jarsigner to sign the instrumented apk
ella.jarsigner.keystore=.android/debug.keystore
ella.jarsigner.storepass=android
ella.jarsigner.keypass=android
ella.jarsigner.alias=androiddebugkey


ella.android.buildtools.dir=~/Library/Android/sdk/build-tools/32.0.0
ella.android.jar=~/Library/Android/sdk/platforms/android-32/android.jar

In the last two lines with the path to these two files.

Could anyone please help me solve this problem?

You need to edit the <path_to_ella>/ella/runtime/GuessDefaultSettingsTask.java file.
You need to set the file path hard, because the dynamic reading doesn't work for everyone..

Your new file have to look like this:

import org.apache.tools.ant.*;
import org.apache.tools.ant.taskdefs.*;

import java.util.*;
import java.io.*;

public class GuessDefaultSettingsTask extends Task
{
	public void execute() throws BuildException
	{
		String sdkPath = findAndroidSDKPath();
		String btPath = getProject().getProperty("ella.android.buildtools.dir");
		if(btPath == null){
			btPath = findAndroidBuildToolsPath(sdkPath);
			System.out.println("path to build-tools directory: "+btPath);			
		}
		File dxPath = new File(btPath, "dx");
		if(!dxPath.isFile())
			throw new Error("The configuration variable android.buildtools.dir is probably not set correctly. Current value is "+btPath);
		getProject().setProperty("ella.android.buildtools.dir", btPath);
		String androidJarPath = getProject().getProperty("ella.android.jar");
		if(androidJarPath == null){
			androidJarPath = findAndroidJarPath(sdkPath);
			if(androidJarPath == null)
				throw new Error("Could not automatically infer path to android.jar. Set ella.android.jar variable in the .settings file.");
			getProject().setProperty("ella.android.jar", androidJarPath);
		}
	}
	
	String findAndroidSDKPath() 
	{
		File sdk = new File("/Users/nicoostendorf1/Library/Android/sdk");
		return sdk.getPath();
	}

	String findAndroidBuildToolsPath(String sdkPath)
	{
		File buildToolsDir = new File("/Users/nicoostendorf1/Library/Android/sdk/build-tools/25.0.0");
		return buildToolsDir.getPath();
	}

	String findAndroidJarPath(String sdkPath)
	{
		File jarfile = new File("/Users/nicoostendorf1/Library/Android/sdk/platforms/android-25/android.jar");
		return jarfile.getPath();
	}
}

Thanks a lot, it worked on my Mac.
