ASM is an all purpose Java bytecode manipulation and analysis framework. It can be used to modify existing classes or to dynamically generate classes, directly in binary form. ASM provides some common bytecode transformations and analysis algorithms from which custom complex transformations and code analysis tools can be built. ASM offers similar functionality as other Java bytecode frameworks, but is focused on performance. Because it was designed and implemented to be as small and as fast as possible, it is well suited for use in dynamic systems (but can of course be used in a static way too, e.g. in compilers).
To build the project, you need to have Java 11+ installed on your system. You can build the project by running the following command:
./gradle/gradlew clean buildAfter the build is complete, you can find the compiled JAR files in the
corresponding build/libs directory of each submodule.
To run only the project tests, you can use the following command:
./gradle/gradlew testTo contribute to the ASM project fork this repository
on GitLab, make changes,
then send us
a merge request.
We will review your changes and apply them to the master branch.
To avoid frustration, before sending us your merge request, please run a full
Gradle build to ensure that your changes do not violate our quality standards:
./gradle/gradlew clean buildAll submodules are checked with googleJavaFormat, Checkstyle and PMD.
If you encounter any issues with the ASM project, please create a new issue on the GitLab issue tracker.
