Build error referencing build.xml and proguard file: "null returned: 1"

Question

While building my PhoneGap app (with the Facebook SDK plugin installed), I encountered this error:

BUILD FAILED C:\adt-bundle-windows-x86_64-20130522\sdk\tools\ant\build.xml:653: The following error occured while executing this line: C:\adt-bundle-windows-x86_64-20130522\sdk\tools\ant\build.xml:698: null returned: 1

Line 653 is:

<do-only-if-manifest-hasCode elseText="hasCode = false. Skipp aidl/renderscript/R.java">

Line 698 is:

proguardFile="${out.absolute.dir}/proguard.txt"

My solutions so far include the following:

1. Ran android update project to force generation of the proguard-project.txt file, as well as update the local.properties and project.properties file.
2. Edited C:\adt-bundle-windows-x86_64-20130522\sdk\tools\ant\build.xml so that all mentions to proguard.txt become proguard-project.txt.
3. ran ant -logfile ./antLogFile.txt release. Here is the log file.

All of my attempts yielded no progress. Why does this error occur? What must I do to build successfully?

Answer 1

For me: I had

edited my config.xml wrongly

. Try undoing your edits or placing a generic config.xml then see if she builds.

Answer 2

Close Eclipse and then run ant clean in your project folder.

Answer 3

Verify your JAVA_HOME variable is correctly set to some path like C:\Program Files\Java\jdk1.7.0_67\ and if the error still goes on, it may be solved going to the build.xml and setting true to the variable fork, or the passed variable ${need.javac.fork}, which sets fork´s value in:

fork="${need.javac.fork}"
