Cannot resolve symble 'R' #284

bjzhou · 2016-11-10T05:18:21Z

使用freeline后有概率导致Android Studio无法识别R.java，必须重新sync gradle一下

lomanyong · 2016-11-11T04:05:59Z

@bjzhou 能够给个复现路径，以及是哪个module的R.java无法识别吗？比如是app module还是library module这样的信息。

bjzhou · 2016-11-11T04:22:22Z

@lomanyong 找到复现路径了，实际包名和build.gradle里applicationId指定的包名不一致时就会出现这个bug，就是app module

lomanyong · 2016-11-11T04:43:28Z

@bjzhou 是在manifest中定义了不一样的包名？还是使用applicationIdSuffix之类的属性呢？

bjzhou · 2016-11-11T05:22:29Z

@lomanyong 改的是app的build.gradle里defaultConfig.applicationId这一项，也就是manifest定义了不一样的包名

lomanyong · 2016-11-11T06:27:47Z

@bjzhou 试了一下，这个case确实比较特殊...还会引发一些其他奇怪的问题...后面单独发个小版本给你测试看看...

Rainbow-556 · 2016-11-25T02:50:46Z

你好，我的项目也是这种情况，在app的build.gradle定义了两个applicationId，其中debug包和正式包的applicationId不一样，所以每次使用freeline构建的时候都识别不了R文件，求解决方法。

lomanyong · 2016-11-25T02:53:36Z

@Rainbow-556 贴出个大概的配置看下？

解决方法就是等待发版吧（预计1-2个小版本内会解决这个问题）...因为这个改动比较特殊...所以还得多测试一下...

Rainbow-556 · 2016-11-25T02:59:35Z

默认自己构建的是innerDebug包，下面是build.gradle的相关部分：

productFlavors{
        official{
            applicationId "com.xxx.app"
            manifestPlaceholders = [PACKAGE:applicationId,APPNAME:"xxx"]
        }
        inner{
            applicationId "com.xxxtest.app"
            manifestPlaceholders = [PACKAGE:applicationId,APPNAME:"xxxtest"]
        }
}

wankey · 2016-11-28T03:19:08Z

0.8.2版本有同样的现象发生。

Manifest中的packageName和applicationId不一致时，干净的项目用freeline第一次编译成功，修改一行代码后再执行freeline，会报出Manifest中的packageName目录下的R.java找不到（IOError: [Errno 2] No such file or directory），同时，AS编辑器中也会找不到R.java。

lomanyong · 2016-11-28T03:25:30Z

@wankey python会报找不到？如果是的话，麻烦贴出日志来看下...

Manifest中的packageName和applicationId不一致是个特殊的case，请耐心等下发版解决吧...

第二次编译时有修改过布局文件等涉及到R文件变更的代码。
如果只是纯代码修改python不会报找不到R文件

lomanyong · 2016-11-28T03:40:00Z

@wankey 感谢提供日志...这个问题的修复这周会发版解决.

wankey · 2016-11-28T03:43:34Z

@lomanyong, 不客气，很期待能解决这个问题。使用freeline在开发过程中节约了我们许多时间。感谢你们！

Rainbow-556 · 2016-11-28T04:47:34Z

确实freeline帮我们节省了很多时间，感谢freeline团队，哈哈

lomanyong · 2016-11-30T13:46:34Z

@bjzhou @Rainbow-556 @wankey hi，这样修改一下你的项目配置，修改版本号为：0.8.2.1611302135

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        ......
        classpath 'com.antfortune.freeline:gradle:0.8.2.1611302135'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

然后执行一下这个命令：

win: gradlew initFreeline -PfreelineVersion=0.8.2.1611302135
linux/mac: ./gradlew initFreeline -PfreelineVersion=0.8.2.1611302135

执行 python freeline.py -v 确认一下 freeline 的版本为：0.8.2.1611302135

最后，重新使用freeline编译看下是否解决了你的问题。

wankey · 2016-12-01T02:02:12Z

@lomanyong,
试过修改代码、布局、资源文件，没有再出现Cannot resolve symble 'R'的现象

lomanyong · 2016-12-01T02:04:00Z

@wankey ok~0.8.3 版本发布后彻底解决这个问题..

Rainbow-556 · 2016-12-01T03:48:32Z

刚刚使用0.8.2.1611302135这个版本测试了，没有出现Cannot resolve symble 'R'的问题，但是会导致我的AS布局不能预览，要clean project之后才可以预览，但是在全构建时，又不能预览了。我换回0.8.2这个版本，就一直能预览。不知道是什么问题....

lomanyong · 2016-12-01T03:52:36Z

@Rainbow-556 不能预览提示什么呢？

Rainbow-556 · 2016-12-01T03:56:01Z

就是在xml布局编辑器的右边都没有出现preview窗口，点击左下角的design也不能预览，并且没有提示信息，预览手机窗口是全黑的，试过更换预览的api版本也没用。

lomanyong · 2016-12-01T04:48:01Z

@Rainbow-556 看了一下貌似没有太多关于这个地方的修改，以前有解决过这个问题。一直出现这个问题吗？

@wankey 你是否有遇见过类似的情况呢？

wankey · 2016-12-01T05:04:40Z

@lomanyong
0.8.2.1611302135中没有出现这个现象

附上AS信息

@lomanyong 我AS版本是2.2.1，使用0.8.2.1611302135版本一直有这种情况，我试过重启AS也没用，看今天我有时间的话我再试试，再来反馈。目前我暂时切换回0.8.2这个版本了。

Rainbow-556 · 2016-12-01T06:37:43Z

@lomanyong 我刚刚把AS升级到2.2.2，然后使用0.8.2.1611302135版本，一切正常，一直能预览，可能是AS版本的原因吧。非常感谢你们修复了不同包名的这个问题

…ibaba#284)

shingohu · 2016-12-21T10:05:35Z

@lomanyong 表示还存在这个问题
版本0.8.4
AS配置

 freeline {
        hack true
        productFlavor 'tt'
        buildScript './gradlew assembleTtDebug'
       // applicationProxy false
    }


 tt {
            applicationIdSuffix ".test"
          
         
            resValue("string", "app_name", "测试环境")
        }


代码飘红,找不到R 可以运行

shingohu · 2016-12-21T10:30:38Z

另外#283 启动时卡住好像也是因为这个去掉 applicationIdSuffix ".test" 一切就正常了

lomanyong · 2016-12-21T10:59:11Z

@shingohu 启动卡主应该跟这个没啥关系...

具体找不到 R.java 的那个过程可以说一下吗？怎么操作的？

shingohu · 2016-12-21T13:40:44Z

@lomanyong
1.我的程序打.test的包就会卡在启动界面,打生产的包就没有问题
2.具体过程不好重现,大概就是运行.test包后,在修改某个Activity,在运行就找不到R.java了,也是生产的包没问题

lomanyong · 2016-12-22T03:32:05Z

@shingohu freeline 只在 debug 包起作用，生产的包一般不行的...

升级Android studio3.0,gradle 后报这个

gradle是 4.3 版本，以前freeline是0.8.7没问题现在都升级为0.8.8出现
