Dapper is a fork of [dagger2](https://github.com/google/dagger),

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:

```bash

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`:

```java

requires dagger;

```

The gradle config is as follows:

```groovy

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

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

```
