Barcode4J does not work after migrating to JasperReports v7

[thomash]

Hello community,

I recently updated JasperReports and managed to export reports.

Unfortunately I experience this error, when exporting a barcode4j-Report:

I already added the dependency jasperreports-barcode4j to my pom.xml. 

 

Are there other steps needed?

Has anyone experienced a similar issue?

[thomash]

This issue seems to be related to creating an Uber JAR with the maven-shade-plugin, because the jasperreports_extension.properties will not be merged due to the fact, that the file exists in several projects now.

solved this issue but another one appeared with and without maven-shade-plugin:

Maybe someone encountered this one?

After setting any errorCorrectionLevel in the Report the report finally works.

 

<element kind="component" uuid="28a4af9a-5de4-45f2-81c2-0545a85f1353" x="280" y="113" width="159" height="114" backcolor="rgba(255, 255, 255, 0.0)">

<component kind="barcode4j:QRCode" errorCorrectionLevel="H">

<codeExpression><![CDATA[$F{NUM_TEST}]]></codeExpression>

</component>

 

However, if you use the Barcode4j-Palette in the Jaspersoft® Studio 7.0.0 - Visual Designer for JasperReports the default setting is, that this parameter is not set in the JRXML. In the designer one can see, that the setting is shown as if the errorCorrectionLevel is set to "L".

Is this maybe a configuration issue of the palette of the new JasperSoft Studio version?
