            Creating objects in Dagger
            Asked 2021-Jun-07 at 10:47

            I'm trying to learn Dagger, and I don't understand how I can actually get an instance of a class without writing a component for it.

            In Guice, this would be as simple as:



            Answered 2021-Jun-07 at 10:47

            Guice use reflection so he is able to build object at runtime and the graph dependency is done during the runtime.

            Dagger use Code generation so the build of the graph dependency is made when you build your application. This code generation will be done only for cleary declared component otherwise dagger would have to generate code for all class of your project (or even your classpath). So that would be totally inefficient (or impossible for complexe object)



            Runtime value injection in Dagger vs. Guice
            Asked 2021-Jun-01 at 18:55

            I'm migrating a project from Guice to Dagger, and I'm trying to understand what to do with injection of values at runtime. Let's say I have a Guice module with the following configure method:



            Answered 2021-Jun-01 at 18:55

            Dagger added its own assisted injection in version 2.31, so there isn't much to change.

            The factory interface needs to be annotated with @AssistedFactory:



            Is there an equivalent for Guice install(new ModuleA) in Dagger?
            Asked 2021-May-27 at 20:33

            I'm trying to migrate a project from Guice to Dagger, and I can't figure out what to do with modules including other modules using install. How would I switch even a really basic example like this to Dagger?

            To make one module include another in Dagger, use includes in your @Module annotation:



            Migrating project from Guice to Dagger
            Asked 2021-May-27 at 18:39

            I want to use Dagger in a project currently configured with Guice. I'm still very new to the concepts of DI, but I see that both Guice and Dagger use @Inject and @Provides notations. I have some understanding of the @Module and @Component annotations and how to set them up, but I'm wondering if the @Inject and and @Provides can basically be left as they are?

            For example, let's say I have this in Guice:



            Answered 2021-May-26 at 20:36

            NOTE: Have not used Dagger but can clarify on Guice side.

            @Provides in Guice is for informing the Guice injector about which method to use to for creating the asked object at build time. for eg : class Parent has implementation in 2 sub classes Child1 and Child2 Now you want to have a logic which defines when to inject Child1 and when to inject child2. This logic can be written in a method which can become the provider for Parent class impl. and to declare this provider method, @Provides annotation is used



            JPro Maven build failing with UncheckedExecutionException
            Asked 2021-May-18 at 20:38

            I am trying to run a simple JavaFX JPro demo project using Maven.

            This is my file structure:



            Answered 2021-May-18 at 20:38

            This happens because the version of JPro you are using doesn't support Java16.

            It works with the newly released version 2021.1.1. (Which wasn't available when the question was asked)



            DI example in Jersey 2.34 with Google Guice 4.2.3
            Asked 2021-May-13 at 09:57

            Please suggest a good example of implementing Dependency Injection using GUICE in a Jersey RESTful API application. Examples on many websites are very old (Implemented somewhere between 2011-2016).



            Answered 2021-May-13 at 09:57

            I got an answer that explains all the logic and solves various problems/conflicts which arise when GUICE is used with Jersey.

            How to make a class's constructor unit testable when its instantiating a Guice module in it?
            Asked 2021-May-11 at 19:59

            I have the below mentioned class in a library module, which the clients will use to interact with database. I have a public constructor that takes a parameter from the user of this library, but the problem with this is that, its a Guice module getting instantiated inside this constructor. So when I try to write a unit test for this DataPersistence clasas, I cannot inject the module. I don't want the real Guice module to be instantiated because that will create database connections and all.

            Can't run Maven 3.6.3 on JDK7
            Asked 2021-May-11 at 07:15

            According to the Maven release history, it should be possible to run any recent version of Maven (at the time of writing anyway) on JDK 7. However, when I try to do so on my Ubuntu 21.04 machine, I get an error: java.lang.UnsupportedClassVersionError: com/google/inject/Module : Unsupported major.minor version 52.0.

            It happens even while running mvn without any parameters in a directory that doesn't contain any Java files or pom.xml file.

            Answered 2021-May-11 at 07:15

            The problem here is that Ubuntu has repackaged Maven which in result produces the issue.

            Apache Oozie throws ClassNotFoundException (org.apache.hadoop.conf.Configuration) during startup
            Asked 2021-May-09 at 23:25

            I built the Apache Oozie 5.2.1 from the source code in my MacOS and currently having trouble running it. The ClassNotFoundException indicates a missing class org.apache.hadoop.conf.Configuration but it is available in both libext/ and the Hadoop file system.

            I followed the 1st approach given here to copy Hadoop libraries to Oozie binary distro.

            I downloaded Hadoop 2.6.0 distro and copied all the jars to libext before running Oozie in addition to other configs, etc as specified in the following blog.


            This is how I installed Hadoop in MacOS. Hadoop 2.6.0 is working fine.

            This looks pretty basic issue but could not find why the jar/class in libext is not loaded.

            • OS: MacOS 10.14.6 (Mojave)
            • JAVA: 1.8.0_191
            • Hadoop: 2.6.0 (running in the Mac)


            Answered 2021-May-09 at 23:25

            I was able to sort the above issue and few other ClassNotFoundException by copying the following jar files from extlib to lib. Both folder are in oozie_install/oozie-5.2.1.

            • libext/hadoop-common-2.6.0.jar
            • libext/commons-configuration-1.6.jar
            • libext/hadoop-mapreduce-client-core-2.6.0.jar
            • libext/hadoop-hdfs-2.6.0.jar

            While I am not sure how many more jars need to be moved from libext to lib while I try to run an example workflow/job in oozie. This fix brought up Oozie web site at http://localhost:11000/oozie/

            I am also not sure why Oozie doesn't load the libraries in the libext/ folder.



            Scala "not found: object com" - should i really add entry in build.sbt if there are no other dependencies?
            Asked 2021-May-08 at 15:03

            I have created basic Scala Play application with play-scala-seed. This project compiles and runs with sbt run. But I have another Scala project that compiles and runs and which I have submitted to my local Ivy repository with command sbt publishLocal. This other project was saved at C:\Users\tomr\.ivy2\local\com.agiintelligence\scala-isabelle_2.13\master-SNAPSHOT as a result of this command.

            Then I imported (exactly so - imported, no just opened) my Play project in IntelliJ and I used Project - Open Module Settings - Project Settings - Libraries to add com.agiintelligence jar from my ivy2 location. After such operations IntelliJ editor recognizes com.agiintelligence classes. That is fine.

            But when I am trying to run my Play application with sbt run, I experience the error message not found: object com that is exactly when compiling import com.agiintelligence line in my Scala controller file of Play application.

            Of course - such error has been reported and resolved with, e.g. object play not found in scala application But that solution suggests to append build.sbt file. My build.sbt file is pretty bare:



            Answered 2021-May-08 at 00:39

            I resolved the error message by adding line in build.sbt file

            libraryDependencies += "de.unruh" %% "scala-isabelle" % "master-SNAPSHOT"

            and by subsequent run of sbt update.

            Error is solved, but the main question still stand - why I had to do this? Why there are tens of dependencies that are not listed in build.sbt and why should I list my dependency in build.sbt and why it is not sufficient to list it Project-Setting--External Libraries in IntelliJ only?

            OK, comment by @Luis_Miguel_Mejía_Suárez gave the explanation, that comment is the actual and expected answer to my question.
