If an extra letter or number pads the name of the source file, the code will not compile. If the first letter of the file is lowercase but the class declaration is uppercase, the code will not compile. Java provides no lenience here - the source filename must exactly match the name used in the class declaration. This Java class must be saved in a file named ThisWillCompile.java - or else it won't compile. If not, the compiler generates the following Java compile time error: The public type problemcode must be defined in its own fileĪ Java class declaration looks like this: public class ThisWillCompile The name of the Java source file, as it resides on the filesystem, must exactly match the name of the public Java class as it is defined in the class declaration.

Top 10 common Java compile errors and how to fix them To help alleviate the frustrations that compile time error often evoke, let's explore the most commonly encountered compile time errors in Java, and some quick ways to fix them. Compile time error messages are notoriously unclear, and troubleshooting such errors can be overwhelming. As such, it's imperative to fix compile time errors in Java as soon as they occur so that code can be pushed into an organization's continuous delivery pipeline, run and tested.Ĭompile time errors in Java are a source of great frustration to developers, especially as they try to learn the language. I hope these tips can help you conquer your Android data binding error challenges.If code doesn't compile, the program is entirely unable to execute. I find this helps when the data binding compiler is not generating my data binding classes like it should be. Some people in online communities have found that if they tell Android Studio to Invalidate Caches and Restart, it can fix the erroneous error. Sometimes, you may not even have an error in your code, but Android Studio incorrectly says that you do. #Uncomment this line to revert to the old compilerĪ2=false 3. I chose to comment it out when I don’t need it, just in case a Version 3 compiler comes along someday. You could leave this setting there and just toggle the Boolean from false to true when you want to go back and forth. To take care of this, in the gradle.properties file, add the setting 2=false to revert to the old compiler. Once you figure out what your compile error is, switch back to Version 2 to restore the speed of your compile. I have found that rolling back to the first version of the data binding compiler can help reveal the real reason your code is not compiling. The incremental build may also be the source of the problem when you have cryptic error messages. Version 2 drastically improved compile times by incrementally creating the binding classes. Starting in version 3.2.1 of Android Studio, the second version of the data binding compiler was turned on by default. Fall Back to the Old Data Binding Compiler Temporarily I was missing a variable definition called viewModel in my layout file. Here, you can see the real reason for my compile error. To see all of the build output, press the Toggle View button. The underlying issue is obscured, and you should look at the entire build output. The default tree view tries to condense the build output into an easy-to-view hierarchy.Īlthough this method allows you to quickly get to your first build error, it doesn’t help if your first build error is a failed import because of problems elsewhere in your code. View All of the Build OutputĪndroid Studio has two different ways to view the build output. If you are getting cryptic errors like error: cannot find symbol import, the following methods may help you figure out what is wrong. There is nothing worse than the compiler telling you something’s wrong in your project but not telling you where. Trying to figure out what is causing data binding errors when you compile your Android project? This post will save you a lot of time and frustration.
