下載-Maven-插件拋出IllegalArgumentException

Question

當我嘗試使用com.googlecode.maven-download-plugin.download-maven-plugin：1.2.1來下載zip文件並將其解壓縮時，出現以下錯誤。 當我將文件下載到Windows或Unix機器時，我嘗試檢查文件權限，但是該權限看起來像正常的（-rw-r--r--）。為什么會引發此錯誤？

<plugin>
    <groupId>com.googlecode.maven-download-plugin</groupId>
    <artifactId>download-maven-plugin</artifactId>
    <version>${download-maven-plugin.version}</version>
    <executions>
        <execution>
            <id>download-sample</id>
            <phase>initialize</phase>
            <goals>
                <goal>wget</goal>
            </goals>
            <configuration>
                <url>${sample-url}</url>
                <unpack>true</unpack>
                <outputDirectory>${project.build.directory}/kit</outputDirectory>
            </configuration>
        </execution>
    </executions>
</plugin>

我目前遇到同樣的問題。 我發現，刪除.m2\\repository\\.cache\\download-maven-plugin ，該插件再次成功運行。

我認為我將改變插件，因為khmarbaise建議。

自從我發布這個答案下載插件后經常出現問題下載文件，我終於切換到了antrun插件：

<artifactId>maven-antrun-plugin</artifactId>
<executions>
    <execution>
        <id>download</id>
        <phase>none</phase><!-- I didn't need to link to phase -->
        <goals>
            <goal>run</goal>
        </goals>
        <configuration>
            <target>
                <echo message="Download file http://fake-url.com/xxx" />
                <get src="http://fake-url.com/xxx" dest="${project.build.directory}/to-file-path.xxx" />
            </target>
        </configuration>
    </execution>
