Cannot compile on Java 8 about jasper-report-maven-plugin

[ardeshirayati]

Hi
I solved that by this config : jasper

<dependency>
	<groupId>net.sf.jasperreports</groupId>
	<artifactId>jasperreports</artifactId>
	<version>5.5.1</version>
	<exclusions>
		<exclusion>
			<groupId>eclipse</groupId>
			<artifactId>jdtcore</artifactId>
		</exclusion>
	</exclusions>
</dependency>

This workaround that involves changing the JDT version seems to solve this problem: http://community.jaspersoft.com/jasperreports-server/issues/3498 (comments 7 & 8).

This workaround didn't work for me

I worked this around by adding this dependency to the plugin execution:

<dependency>
    <groupId>net.sf.jasperreports</groupId>
    <artifactId>jasperreports</artifactId>
    <version>6.1.0</version>
</dependency>

and thus replacing the 5.2.0 version specified in plugin's pom.xml.

So now my plugin configuration looks like this:

<plugin>

    <groupId>com.alexnederlof</groupId>
    <artifactId>jasperreports-plugin</artifactId>
    <version>1.6</version>

    <executions>
        <execution>
            <phase>process-sources</phase>
            <goals>
                <goal>jasper</goal>
            </goals>
        </execution>
    </executions>

    <configuration>
        <compiler>net.sf.jasperreports.engine.design.JRJdtCompiler</compiler>
        <sourceDirectory>src/main/resources/reports</sourceDirectory>
        <outputDirectory>${project.build.directory}/classes/reports</outputDirectory>
        <outputFileExt>.jasper</outputFileExt>
        <xmlValidation>true</xmlValidation>
        <verbose>true</verbose>
        <numberOfThreads>2</numberOfThreads>
    </configuration>

    <dependencies>

        <!--

        -->
        <dependency>
            <groupId>net.sf.jasperreports</groupId>
            <artifactId>jasperreports</artifactId>
            <version>6.1.0</version>
        </dependency>

        <!-- other project dependencies ->

    </dependencies>

</plugin>

I guess the solution would be then to upgrade net.sf.jasperreports:jasperreports dependency to something from the 6.x.x tree.

Works for me too with the workaround by mkielar

2.0 works for me to in java-8
