android-sdk/tools/ant/build.xml:698: null returned

问题:

I'm trying to test a Android release build to make sure nothing unexpected occurs. While trying to build with ant from the command line:

/usr/local/bin/ant release
...

BUILD FAILED
.../android-sdk/tools/ant/build.xml:653: The following error occurred while executing this line:
.../android-sdk/tools/ant/build.xml:698: null returned: 1

When I look at build.xml:698, the issue is with the Proguard file below.

<aapt executable="${aapt}"
    command="package"
    verbose="${verbose}"
    manifest="${out.manifest.abs.file}"
    originalManifestPackage="${project.app.package}"
    androidjar="${project.target.android.jar}"
    rfolder="${gen.absolute.dir}"
    nonConstantId="${android.library}"
    libraryResFolderPathRefid="project.library.res.folder.path"
    libraryPackagesRefid="project.library.packages"
    libraryRFileRefid="project.library.bin.r.file.path"
    ignoreAssets="${aapt.ignore.assets}"
    binFolder="${out.absolute.dir}"
    proguardFile="${out.absolute.dir}/proguard.txt">
    <res path="${out.res.absolute.dir}" />
    <res path="${resource.absolute.dir}" />
</aapt>

My project had a proguard-project.txt. After renaming to proguard.txt, the problem persists.

I'm happy to omit the Proguard step since I don't use it.

How do I resolve this issue?

In case it matters:

$ /usr/local/bin/ant -v
Apache Ant(TM) version 1.9.4 compiled on April 29 2014

I needed to upgrade ant due to an error, but I don't recall what the error was. I seem to recall it had something to do with Java 7 or Java 8.

回答1:

Had the same error. found the fix at https://stackoverflow.com/a/23774435. close eclipse. and run 'ant clean'

回答2:

change project.properties in appcompat directory to 'target=android-21', or Close Eclipse and then run ant clean in your project folder , if the first doesnt work

回答3:

Just happened to me and what I did to solved this is by removing the platform and re-adding it again.

cordova platform rm android

then

cordova platform add android

回答4:

I know that this problem can be caused by many things, however in my case I couldn't build because of a malformed config.xml. I forgot to add the gap: namespace which was used to build with build.phonegap.com

<widget id="appid" version="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:gap="http://phonegap.com/ns/1.0" xmlns:cdv="http://cordova.apache.org/ns/1.0">

I got the same error. The problem is in the 64-bit library. Try to install:

sudo apt-get install lib32z1

Fixed it by removing some png files that I had in res folder.
