A few common ones 29are listed here. 30 31### I get a compilation error 32 33While you can check the build status on Github to confirm, 34the project correctly builds and passes tests at all times. 3590% of the time it's due to using an old version of Java. Version 3.4+ require Java 8. 36Use earlier versions with Java 7 and earlier. 37 38### This barcode doesn't decode 39 40Not all images will decode. All else equal, more is better, but this is not accepted as a bug 41report. A pull request that makes changes to make the barcode decode without decreasing the net 42number of barcodes recognized in the unit tests may be considered. 43 44## Licensing 45 46Contributions via GitHub pull requests are gladly accepted from their original author. 47Along with any pull requests, please state that the contribution is your original work and 48that you license the work to the project under the project's open source license. 49Whether or not you state this explicitly, by submitting any copyrighted material via 50pull request, email, or other means you agree to license the material under the project's 51open source license and warrant that you have the legal authority to do so. 52
