My issues are:

#1 generated sources aren't available for gwt compilation

running:

mvn compile

no errors are found in the compilation phase, dagger 2 generated sources land in target/generated-sources/annotations/

However running:

mvn compile gwt:compile

GWT compilation outputs the following error:

[ERROR] Errors in 'file:/path/to/project/src/main/java/path/to/project/client/ProjectEntryPoint.java'
[INFO] [ERROR] Line 79: No source code is available for type path.to.project.client.Dagger_ProjectComponent; did you forget to inherit a required module?
[INFO] [ERROR] Hint: Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly

the problem seems related with the fact that GWT compilation isn't including the generated sources, as target/generated-sources/annotations/ isn't included in the classpath of the GWT compiler. The project class paths that are included in GWT compile command are:

/path/to/project/target/tmp/WEB-INF/classes
/path/to/project/target/src/main/java

Which version of the maven-compiler-plugin are you using? m-compiler-p didn't add the generated-sources to the compileSourceRoots until version 3.2: https://jira.codehaus.org/browse/MCOMPILER-157, so you had to use the build-helper-maven-plugin to add it.
