Dapper is a fork of dagger2, with some modifications:

• gradle project with JUnit 5 tests
• full jpms support with module-name: dagger
• removed the producers extension and all producers annotations like @ProductionComponent
• remove kotlin special-casing and the dependency on xprocessing
• remove gwt special-casing and guava special casing, like support for c.g.c.b.Optional
• remove internal guava dependency
• remove the experimental_turbine_hjar compiler option

Dapper uses jakarta.inject annotations and ignores their javax.inject counterparts. Existing dagger projects can use the following script to replace the imports:

for F in `find src/main/java -name "*.java"`; do
  for N in Singleton Scope Inject Qualifier Provider; do
    sed -i .bak "s/^import javax.inject.$N;$/import jakarta.inject.$N;/" $F
  done
  rm ${F}.bak
done

If you have a modular java build, add this to module-info.java:

requires dagger;

The gradle config is as follows:

implementation('io.github.jbock-java:dapper:2.41.2')
annotationProcessor('io.github.jbock-java:dapper-compiler:2.41.2')
