小编Sae*_*.re的帖子

我刚刚将项目迁移到androidx并启用了jetifier。

现在，当我要构建项目时，出现以下错误：“尚未执行转换” Gradle同步完成，没有任何错误，但是构建失败。

该任务执行失败：

Transform org.eclipse.jdt.core.jar (org.eclipse.jdt:org.eclipse.jdt.core:3.10.0) with IdentityTransform

堆栈跟踪 ：

我的工作站：

Build: 3.3 Canary 13
Android Gradle Plugin: 3.3.0-alpha13
Gradle: 4.10.1
BuildToolsVersion : 28.0.3
Compile/Targer sdkVersion : …

我将支持库从r20更新到r21,现在当我运行我的应用程序时super.onCreate,我的主要活动中出现此错误:

我的theme.xml:

<style name="AppBaseTheme" parent="Theme.AppCompat">
</style>

<style name="AppTheme" parent="AppBaseTheme">
    <item> ... </item>
</style>

在清单中:

android:theme="@style/AppTheme"

问题是什么 ？

谢谢
