I am trying to build an Android app instrumenting tool called Ella from https://github.com/saswatanand/ella
When I was trying to build it using ant, it shows this error:

However, in the settings file, my android build tools is setted to location:
/Users/sioyoo/Library/Android/sdk/build-tools/32.0.0
where is actually where I kept my android build tools.
Can anyone help me with this? I am using MacOS to build this tool.

I solved the Problem by editing the <path_to_ella>/ella/runtime/GuessDefaultSettingsTask.java file as follows:
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[] sCmdExts = {""}; //TODO: support windows?
StringTokenizer st = new StringTokenizer(System.getenv("PATH"), File.pathSeparator);
String path, sFile;
while (st.hasMoreTokens()) {
path = st.nextToken();
for (String sExt : sCmdExts) {
sFile = path File.separator "android" sExt;
File file = new File(sFile);
if (file.isFile()) {
return file.getAbsoluteFile().getParentFile().getParent();
}
}
}
throw new RuntimeException("The executable 'android' is not in the path");*/
}
String findAndroidBuildToolsPath(String sdkPath)
{
/*File buildToolsDir = new File(sdkPath, "build-tools");
//find the latest version
String latestVersion = null;
for(String v : buildToolsDir.list()){
if(latestVersion == null || v.compareTo(latestVersion) > 0){
latestVersion = v;
}
}
assert latestVersion != null : "Build tools not found";
//return buildToolsDir.getPath() File.separator latestVersion;*/
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();
/*File platformsDir = new File(sdkPath, "platforms");
String latestVersion = null;
for(File v : platformsDir.listFiles()){
if(!v.getName().startsWith("android-"))
continue;
File androidJar = new File(v, "android.jar");
if(androidJar.isFile())
return androidJar.getPath();
}
return null;*/
}
}You have to edit the File paths like you need it!
