eclipse将javaweb项目导出成war包时报错怎么办

Question

下面是报错信息CONFIGURE SUCCESSFUL in 18sErrors occurred while build effective model from C:\Users\27107\.gradle\caches\modules-2\files-2.1\com.google.zxing\core\3.3.3\3fc07a37b124d3f9e134854b4c7bf7dc120bcae7\core-3.3.3.pom:    'dependencyManagement.dependencies.dependency.systemPath' for com.google.android:android:jar must specify an absolute path but is /${env.ANDROID_HOME}/platforms/android-22/android.jar in com.google.zxing:core:3.3.3Errors occurred while build effective model from C:\Users\27107\.gradle\caches\modules-2\files-2.1\com.google.zxing\javase\3.3.3\dd6a981a04a79aa686515a11cd09d049e202a32\javase-3.3.3.pom:    'dependencyManagement.dependencies.dependency.systemPath' for com.google.android:android:jar must specify an absolute path but is /${env.ANDROID_HOME}/platforms/android-22/android.jar in com.google.zxing:javase:3.3.3zxing是我用来生成二维码需要的jar包，不能删除，但是这样虽然导出成war包了，在Tomcat中却运行不起来，求大神指点
