java - 意外的顶级异常

Question

在我的 gradle 文件中，我目前有以下内容:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile files('libs/itextg-5.5.4.jar')
}

有了上面的内容，一切都运行正常。当我添加 compile 'com.itextpdf.tool:xmlworker:5.4.0' 行时，出现以下错误:

com.android.dex.DexException: Multiple dex files define Lcom/itextpdf/awt/geom/AffineTransform;
    at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:596)
    at com.android.dx.merge.DexMerger.getSortedTypes(DexMerger.java:554)
    at com.android.dx.merge.DexMerger.mergeClassDefs(DexMerger.java:535)
    at com.android.dx.merge.DexMerger.mergeDexes(DexMerger.java:171)

    at com.android.dx.command.dexer.Main.main(Main.java:215)
    at com.android.dx.command.Main.main(Main.java:106)

我该如何解决？

Answer 1

该异常意味着有多个依赖项/库定义了 com/itextpdf/awt/geom/AffineTransform 类。

确保您没有重复的依赖项。
