摇篮：如何从JScience JAR依赖排除javax.realtime包（多DEX定义） [英] Gradle: How to exclude javax.realtime package from JScience jar dependency (Multiple dex define)

问题描述

我在我的Andr​​oid应用程序中使用的摇篮，我想用JScience库的依赖。我已经添加了库是这样的：

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'
}

但是在编译时出现错误：

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.merge.DexMerger.mergeDexes(DexMerger.java:170)
    at com.android.dx.merge.DexMerger.merge(DexMerger.java:188)
    at com.android.dx.command.dexer.Main.mergeLibraryDexBuffers(Main.java:439)
    at com.android.dx.command.dexer.Main.runMonoDex(Main.java:287)
    at com.android.dx.command.dexer.Main.run(Main.java:230)
    at com.android.dx.command.dexer.Main.main(Main.java:199)
    at com.android.dx.command.Main.main(Main.java:103)

这是因为在项目复制 javax.realtime 包引起的，一个是JDK的一部分，并且第二个是在Jscience库。我试图从Jscience库这样在摇篮中删除这个包：

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'
}

但是，这并没有帮助。所以，这包仍然存在依赖关系。

But that didn't help. So, that package is still exists in dependencies.

有什么办法我怎么可以从罐子上编译时排除包？

Is there any way how I can exclude a package from jar on compile time?

推荐答案

在情况下任何人都需要，问题是在 Javolution 依赖从 JScience 库。他们俩做一个哈瓦 javax.runtime 包。不包括 Javolution 有固定的问题对我来说。

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'
}
