如何在Ant任务失败时阻止Maven构建失败？

Question

我使用的FTP Ant任务与Maven的antrun-插件

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <executions>
        <execution>
            <id>ftp</id>
            <phase>generate-resources</phase>
            <configuration>
                <tasks>
                    <ftp action="get"
                         server="${ftp.server.ip}"
                         userid="${ftp.server.userid}"
                         password="${ftp.server.password}"
                         remotedir="${ftp.server.remotedir}"
                         depends="yes" verbose="yes"
                         skipFailedTransfers="true"
                         ignoreNoncriticalErrors="true">
                        <fileset dir="target/test-classes/testdata">
                            <include name="**/*.html" />
                        </fileset>
                    </ftp>
                </tasks>
            </configuration>
            <goals>
                <goal>run</goal>
            </goals>
        </execution>
    </executions>
...

问题是当$ {ftp.server.remotedir}文件夹不存在时,我的构建失败.
我试图指明

skipFailedTransfers="true"
ignoreNoncriticalErrors="true

但这些并没有解决问题,而且构建仍然失败.

An Ant BuildException has occured: could not change remote directory: 550 /myBadDir: The system cannot find the file specified.

您是否知道如何指示我的maven构建不关心此Ant任务错误/或如何指示Ant在丢失目录时不会失败？

彼得的解决方案有效.
如果你有问题的话

[INFO] Error configuring: org.apache.maven.plugins:maven-antrun-plugin. Reason: java.lang.NoSuchMethodError: org.apache.tools.ant.util.FileUtils.close(Ljava/io/InputStream;)V

只需从ant-contrib中排除ant

<dependency>
    <groupId>ant-contrib</groupId>
    <artifactId>ant-contrib</artifactId>
    <version>${ant-contrib.ver}</version>
    <exclusions>
        <exclusion>
            <groupId>ant</groupId>
            <artifactId>ant</artifactId>
         </exclusion>
    </exclusions>
</dependency>

在这种情况下,也许你需要更像Ant,而不是像Maven.

这是一个解决方案.使用ant-contrib trycatch任务.这是一个示例pom.xml.将代码块复制到名为的文件pom.xml并运行mvn validate以查看它是否有效.
