            How to display Vietnamese in PDF what exported by Jasper report correctly?
            Asked 2019-Aug-12 at 08:14

            I am using these dependencies



            Answered 2019-Jul-26 at 19:09

            Try this:

            1. Do not set a PDF Font Name for the font family that you created with the Arial ttf. You don't want to use Helvetica because it doesn't include glyphs for Vietnamese characters. Leave it empty so that the Arial ttf is used in PDF.
            2. Set the PDF Encoding for the font family to Identity-H (Vietnamese uses horizontal writing).
            3. The screenshot shows that the font family is called "times", so you'll have to use for the text element.

            This will result in the Arial ttf being embedded in the PDF file (a subset of it actually) and used for the text. Therefore the PDF would show the Vietnamese characters, as long as the Arial ttf includes glyphs for them (and my Arial ttf copy does).

            If for some reason you don't want to embed Arial in the PDF file, you can also use the DejaVu fonts included in net.sf.jasperreports:jasperreports-fonts:6.9.0, for instance

            You might also want to set the net.sf.jasperreports.default.pdf.encoding property to Identity-H, if you generally want to embed fonts in PDFs, or just leave it unset and specify the PDF encoding for each font family.



            Migrating from Gradle 4 to 5. How to get mapstruct working with it
            Asked 2019-May-16 at 15:23

            We've use mapstruct for approx 1.5 years with various Gradle versions - latest gradle 4.10.2. We want to switch to Gradle 5.4.1, which works with everything except mapstruct. Our working setup was not clean. Hence decided to start over. Old working setup was a hybrid form of the example on Github and the now obsolete setup.

            Started again with as a base. Have this strong feeling this is NOT compatible with Gradle 5. Release notes Gradle 5 states: Gradle will no longer automatically apply annotation processors that are on the compile classpath — use CompileOptions.annotationProcessorPath instead. Tried to do it as described in This works for 4.10.2. With Gradle 5 this results in the following error: Execution failed for task ''. Cannot specify -processorpath or --processor-path via CompileOptions.compilerArgs. Use the CompileOptions.annotationProcessorPath property instead.

            We have a multi-project setup. In the project 'rest' the sanitized build.gradle looks like this:

            How to get all elements with an annotation in an IntelliJ incremental build?
            Asked 2019-May-15 at 09:08

            I'm writing an annotation processor which needs to collect all the classes with a certain annotation in the current module and write a class referencing each of them.

            To simplify a bit, given these source files:

            src/main/java/org/example/ ...


            Answered 2019-May-15 at 09:08

            One way to solve this issue is use some sort of a registry in between builds, you can for example store the types annotated in a service like style in meta-inf

            So in your processor you defer the code generation until the processing last round, and after generating your code you store the types in a file into a file under the META-INF



            How does AssistedInject for Dagger 2 work?
            Asked 2018-Dec-16 at 16:45

            The AssitedInject library from Square is actually an annotation processor that generates Dagger 2 modules. Dagger 2 is also an annotation processor.

            And as I know there is no way to control the order of processors execution.

            In this example (see snippet below) you can see that the module has dependency on generated by AssistedInject class AssistedInject_MainModule. So in case if Dagger 2 will run first the build should fail because of at this moment AssistedInject_MainModule does not exist.

            But it can be compiled. How does it work?



            Answered 2018-Dec-16 at 16:45

            And as I know there is no way to control the order of processors execution.

            I did not look into how either Dagger 2 or AssistedInject work under the hood, but in general Annotation Processing is done in multiple rounds.

            Annotation processing happens in a sequence of rounds. On each round, a processor may be asked to process a subset of the annotations found on the source and class files produced by a prior round.

            Files get generated during those rounds, but validation (and errors) happens on a later or last round, when every file was generated and processed. This is also mentioned on a second answer on the question you linked. Someone also wrote a detailed answer about how rounds work on a different question.



            PITest cannot find tests
            Asked 2018-Dec-09 at 04:56

            Our projects are all set up with a master parent for the entire company. For the project I'm working on, we have a root pom that references that parent with many modules underneath it. Attempting to use PITest with any one of these modules individually, or at the root module results in no test being run.



            Answered 2017-Apr-01 at 03:04

            Apparently I just had to wipe pitest from my maven repo. It repulled the jars and it worked. It seemed to have been holding onto settings, even when I had removed PITest entirely from my poms.

            edit: apparently I'm an idiot. I had mvn clean org.pitest:pitest-maven:mutationCoverage which of course wipes my target directory before attempting to find the classes.

            Answered 2018-Oct-18 at 15:19

            Instead of using Intellij IDEA, you should configure your build process entirely in gradle. This way it will be IDE-independent, and IDEA supports auto-sync with the gradle project.

            In gradle you can try something like this, and then run the gradle 'build' task (or 'classes' task to only compile source):



            maven-compiler-plugin 3.6.0 doesn't compile generated sources from annotations
            Asked 2018-Mar-09 at 19:04

            We just upgraded our JBoss from 6.1.0 to Wildfly 10.1, and made a variety of associated upgrades to modules and artifact versions and so on. In one module this caused our cobertura compiles to fail with a compiler error. I found IllegalStateException in Hibernate metamodel generation with maven and upgraded to maven-compiler-plugin 3.6.0 (from 3.1). This seemed to resolve my problem, but only on a local basis. I can compile the module for cobertura, but it turns out to cause a new problem.

            Some of the annotation-generated sources for this module are used by another module, and the class files aren't found. What changed? The generated-sources directory contains the java files, but the classes aren't compiled.

            It looked at one point like changing the build-helper phase to generate-sources from process-sources helped, but that failed subsequently.

            Is there something else that needs to be changed because of changes between 3.1 and 3.6.0? (I'm not familiar with how to process annotations - I'm just the Cobertura support guy.)

            pom file:



            Answered 2018-Mar-09 at 19:04

            I resolved this by removing the -proc:none compiler argument from the compiler plugin. With that present none of the generated sources were being compiled at all. With the 3.1 plugin I had to have that, but with 3.6.0 I can't.

            I also tried to implement the answer by making the compilerArg specific to the default-compile phase, but that didn't compile the generated sources. If I didn't reuse the default-compile id the build worked and gave me generated class files, but it ran two compile phases, with the -proc:none one second, which seemed redundant.

            The final pom section for the compiler looks like this:
