org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:mergeDebugResources'.-优快云博客

这篇博客主要介绍了在构建Gradle项目时遇到的TaskExecutionException问题，特别是关于':app:mergeDebugResources'任务执行失败的情况。问题根源通常在于文件后缀名的改动，如.jpg被改为.png，或者是9patch图片导致的。文章提供了相应的解决策略。

问题原因

1.构建Gradle的时候，Gradle会去检查一下是否修改过文件的后缀名；
2.一般大多数是出现在图片上，.jpg修改成了.png就会出现这个问题；
3.9patch图片也可能出现这个问题。

解决方法

在这里插入图片描述

aaptOptions {
        cruncherEnabled = false
        useNewCruncher = false
    }
