为什么jasperreports-maven-plugin需要itext：itext：jar：4.2.0？ [英] Why does jasperreports-maven-plugin needs itext:itext:jar:4.2.0?
问题描述
从今天起我们无法再构建我们的jasper文件了。我们使用jasperreports-maven-plugin。
Since today we can't build our jasper file any more. We use the jasperreports-maven-plugin for this.
在maven 2.2.1中，这个配置如下：
In maven 2.2.1, this was configured like this:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jasperreports-maven-plugin</artifactId>
<version>1.0-beta-2</version>
<executions>
<execution>
<goals>
<goal>compile-reports</goal>
</goals>
<configuration>
<sourceDirectory>${basedir}/src/main/resources/reports</sourceDirectory>
<outputDirectory>>${project.build.directory}/classes/reports</outputDirectory>
</configuration>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>net.sf.jasperreports</groupId>
<artifactId>jasperreports</artifactId>
<version>5.5.1</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>compile</scope>
</dependency>
</dependencies>
<configuration>
<sourceDirectory>C:\Windows\TEMP/src/main/resources/reports</sourceDirectory>
<outputDirectory>C:\Windows\TEMP\target/classes/reports</outputDirectory>
</configuration>
</plugin>
但是，如上所述，从今天开始，我们遇到了这个构建错误：
But, as said, since today, we got this build error:
...
Downloading: http://repo1.maven.org/maven2/itext/itext/4.2.0/itext-4.2.0.jar
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Failed to resolve artifact.
Missing:
----------
1) itext:itext:jar:4.2.0
Try downloading the file manually from the project website.
Then, install it using the command:
mvn install:install-file -DgroupId=itext -DartifactId=itext -Dversion=4.2.0 -Dpackaging=jar -Dfile=/path/to/file
Alternatively, if you host your own repository you can deploy the file there:
mvn deploy:deploy-file -DgroupId=itext -DartifactId=itext -Dversion=4.2.0 -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]
Path to dependency:
1) org.codehaus.mojo:jasperreports-maven-plugin:maven-plugin:1.0-beta-2
2) jasperreports:jasperreports:jar:1.2.0
3) itext:itext:jar:4.2.0
我认为另一个问题（来自itext的jasper-reports中的依赖性错误）与他的相关。我尝试使用Meher的解决方案来使用maven 3.2.3。这似乎是一个解决方案，但我们无法升级（现在）到这个maven版本。所以我需要另一种解决方案来解决这个问题。有任何想法吗？我已经尝试排除依赖项并使用固定版本，但我还没有成功完成构建。我的意思是：
I think another question (Dependency error in jasper-reports from itext) is related to his. And I tried the solution of Meher to use maven 3.2.3. This seems to be a solution, but we can't upgrade (now) to this maven version. So I need another solution to resolve this issue. Any ideas? I already tried to exclude dependencies and use fixed versions, but I haven't managed to succeed my build. What I mean is this:
<!-- Compile jasper reports -->

</plugin>
为什么插件仍在搜索itext：itext：jar：4.2.0？有什么想法或建议可以解决这个问题吗？
Why is the plugin still searching for itext:itext:jar:4.2.0? Any ideas or suggestions to solve this?
谢谢！
推荐答案
我通过使用ant构建我的jasper报告解决了我的问题。所以我跳过了这个插件。
I resolved my issue by using ant to build my jasper report. So I skipped the plugin.
我的ant任务看起来像这样：
My ant task looks like this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>${maven-antrun-plugin.version}</version>
<executions>
<execution>
<id>compile-jasper-reports</id>
<goals>
<goal>run</goal>
</goals>
<phase>generate-sources</phase>
<configuration>
<target>
<echo message="Start compile of jasper reports"/>
<mkdir dir="${project.build.directory}/classes/reports"/>
<taskdef name="jrc" classname="net.sf.jasperreports.ant.JRAntCompileTask" classpathref="maven.compile.classpath" />
<jrc srcdir="${basedir}/src/main/resources/reports"
destdir="${project.build.directory}/classes/reports"
tempdir="${project.build.directory}/classes/reports"
keepjava="true"
xmlvalidation="true">
<classpath refid="maven.compile.classpath"/>
<include name="**/*.jrxml"/>
</jrc>
</target>
</configuration>
</execution>
</executions>
</plugin>
