Closed 7 years ago.
When I was trying to build an android project on Centos 6.6 64bit, it failed with unclear message. I want to share my solution that worked so far. The error message doesn't quite clearly inform the culprit. It turn out that appt tool uses native libraries from the OS. After tracking down the dependencies, I ran this to install them:
sudo yum install -y glibc.i686 zlib.i686 libgcc.i686 libstdc++.i686
I got these messages at first attempt:

Check this answer to a previous post: https://stackoverflow.com/a/21505268
It says you need to install lib32z1.
sudo apt-get install lib32z1

Here's my software configuration:
I used JDK8u45 (I also set the path for JAVA_HOME)
I used Netbeans 8.0.2 for the IDE
I downloaded the Android SDK with API21 in it (I also set the path for ANDROID_HOME)
I downloaded Gradle2.4 (I also set the path for GRADLE_HOME)
I used Windows XP for the OS (32 bit)
What could be the cause of that error?
Here's the build.gradle:
buildscript {

I had the same problem now it's solved .Now I am able to compile and make my android apk .
So these are the steps I followed
Make sure you have updated your sdk manager -> support library
to latest version (23.1.1) it was the latest for me when I posted this
answer. This will update
H:\sdk\extras\android\support\multidex files
Make sure you add your android sdk location in build.gradle
androidSdk='H:/ADT BUNDLE/sdk'
like this
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'org.javafxports:jfxmobile-plugin:1.0.0-b9'
}
}
apply plugin: 'org.javafxports.jfxmobile'
repositories {
jcenter()
}
mainClassName = 'com.fff.Fff'
jfxmobile {
android {
manifest = 'src/android/AndroidManifest.xml'
androidSdk='H:/ADT BUNDLE/sdk'
}
}
If you are working in a 32 bit PC
Set environment variable name JAVA_OPTIONS with value Xmx1024M
If you are working in a 64 bit PC
make sure you install JDK that is 64 bit and not 32 bit JDK

If you don't use boot repackage you can simply disable bootRepackage tasks by adding this line into your build.gradle file:
bootRepackage.enabled = false
Otherwise you need to specify the main class:
bootRepackage {
mainClass = 'youPackage.Application'
}
You can find more instructions in this link
Share your build.gradle if you still have problem.

From Spring Boot release 2.0 M1 the bootRepackage task has been replaced with bootJar and bootWar tasks.
