没找到类“java.util.concurrent.CompletableFuture”

Question

我使用CircleCI来测试一个Android项目 - 我最近添加了一个Java 8 api的使用：java.util.concurrent.CompletableFuture现在我得到了java.lang.ClassNotFoundException: Didn't find class "java.util.concurrent.CompletableFuture"。我使用了circleci/android:api-27-alpha我理解的java.lang.NoClassDefFoundError: Failed resolution of: Ljava/util/concurrent/CompletableFuture; at com.jumpitt.workmentor.TestUtils.login(TestUtils.java:24) at com.jumpitt.workmentor.MainActivityTest.onSyncClicked(MainActivityTest.java:94) at java.lang.reflect.Method.invoke(Native Method) at java.lang.reflect.Method.invoke(Method.java:372) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:26) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:27) at android.support.test.internal.statement.UiThreadStatement.evaluate(UiThreadStatement.java:55) at android.support.test.rule.ActivityTestRule$ActivityStatement.evaluate(ActivityTestRule.java:270) at android.support.test.internal.statement.UiThreadStatement.evaluate(UiThreadStatement.java:55) at org.junit.rules.RunRules.evaluate(RunRules.java:20) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.junit.runners.Suite.runChild(Suite.java:128) at org.junit.runners.Suite.runChild(Suite.java:27) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at org.junit.runner.JUnitCore.run(JUnitCore.java:115) at android.support.test.internal.runner.TestExecutor.execute(TestExecutor.java:59) at android.support.test.runner.AndroidJUnitRunner.onStart(AndroidJUnitRunner.java:262) at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1853) Caused by: java.lang.ClassNotFoundException: Didn't find class "java.util.concurrent.CompletableFuture" on path: DexPathList[[zip file "/system/framework/android.test.runner.jar", zip file "/data/app/com.jumpitt.workmentor.test-1/base.apk", zip file "/data/app/com.jumpitt.workmentor-1/base.apk"],nativeLibraryDirectories=[/data/app/com.jumpitt.workmentor-1/lib/arm, /vendor/lib, /system/lib]] at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:56) at java.lang.ClassLoader.loadClass(ClassLoader.java:511) at java.lang.ClassLoader.loadClass(ClassLoader.java:469) ... 36 more Suppressed: java.lang.ClassNotFoundException: java.util.concurrent.CompletableFuture at java.lang.Class.classForName(Native Method) at java.lang.BootClassLoader.findClass(ClassLoader.java:781) at java.lang.BootClassLoader.loadClass(ClassLoader.java:841) at java.lang.ClassLoader.loadClass(ClassLoader.java:504) ... 37 more Caused by: java.lang.NoClassDefFoundError: Class not found using the boot class loader; no stack available 图片。

我已经尝试在工作中打印java版本，对我来说看起来很好。 is based on JKD8

有没有人对可能发生的事情有任何指示？

在android studio中，即时运行会影响您的代码

尝试通过以下方式禁用它：

档案 - ＆gt;设置 - ＆gt;构建，执行，部署 - ＆gt;即时运行
