I'm using Gradle in my Android application an I would like to use the JScience library dependency. I have added the library this way:
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
compile 'org.jscience:jscience:4.3.1'
testCompile group: 'junit', name: 'junit', version: '4.11'
}
But in the compile time I get the error:
UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dex.DexException: Multiple dex files define Ljavax/realtime/MemoryArea;
at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:594)
at com.android.dx.merge.DexMerger.getSortedTypes(DexMerger.java:552)
at com.android.dx.merge.DexMerger.mergeClassDefs(DexMerger.java:533)

at com.android.dx.command.dexer.Main.main(Main.java:199)
at com.android.dx.command.Main.main(Main.java:103)
This is caused because of duplicating javax.realtime
packages in project, one is a part of JDK, and the second one is in the Jscience library. I have tried to remove this package from Jscience library this way in Gradle:
sourceSets {
main {
java {
exclude 'javax/realtime/**'
}
}
}
configurations {
all*.exclude group: 'javax.realtime'
}
But that didn't help. So, that package is still exists in dependencies.
Is there any way how I can exclude a package from jar on compile time?
In case anybody needed, the problem was in Javolution
dependency from JScience
library. They both do hava a javax.runtime
package. Excluding the Javolution
has fixed the issue for me.
compile ('org.jscience:jscience:4.3.1') {
exclude group: 'org.javolution', module: 'javolution'
}
