maven exec插件：可以将命令输出写入文件

Question

我想使用maven exec插件来将命令输出写入文件， 我只能通过运行插件正在调用的shell命令来做到这一点。

这是shell脚本：

git rev-parse --abbrev-ref HEAD > branch.txt

这是我的pom.xml：

        <groupId>org.codehaus.mojo</groupId>
        <artifactId>exec-maven-plugin</artifactId>
        <version>1.2</version>
        <inherited>false</inherited>
        <dependencies>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-instrument</artifactId>
                <version>5.3.21</version>
            </dependency>
        </dependencies>
        <executions>
            <execution>
                <phase>validate</phase>
                <goals>
                    <goal>exec</goal>
                </goals>
            </execution>
        </executions>
        <configuration>
            <executable>gitbranch.sh</executable>
            <workingDirectory>${basedir}</workingDirectory>
        </configuration>
    </plugin>

试图以命令而不使用脚本时，我无法写入文件：

        <configuration>
            <executable>git</executable>
            <outputFile>branching.txt</outputFile>
            <arguments>
                <argument>rev-parse</argument>
                <argument>--abbrev-ref</argument>
                <argument>HEAD</argument>
            </arguments>
            <workingDirectory>${basedir}</workingDirectory>
        </configuration>

我还尝试运行 echo“ sosings”＆gt; file.txt 使用此插件，但没有任何内容在文件中写入任何内容。

这可能不会直接回答您的问题，但我使用做您想做的同样的事情。我有：

        <plugin>
            <groupId>pl.project13.maven</groupId>
            <artifactId>git-commit-id-plugin</artifactId>
            <version>2.2.6</version>

            <executions>
                <execution>
                    <phase>validate</phase>
                    <goals>
                        <goal>revision</goal>
                    </goals>
                </execution>
            </executions>

            <configuration>
                <useNativeGit>true</useNativeGit>
                <dateFormat>yyyy-MM-dd'T'HH:mm:ssXXX</dateFormat>
                <dotGitDirectory>${project.basedir}/.git</dotGitDirectory>
                <generateGitPropertiesFile>true</generateGitPropertiesFile>
                <failOnNoGitDirectory>false</failOnNoGitDirectory>
            </configuration>
        </plugin>

在我的 build/plugins 我的 pom.xml 的部分。运行此操作时，我将获取名为 git.properties 在我的 target/class/class 目录中生成的

：

import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;

public class VersionInfo {


    public String getVersionString() {
        try {
            Properties properties = getGitProperties();

            boolean isDirty = false;

            String gitDirty = properties.getProperty( "git.dirty" );
            if( gitDirty != null )
                isDirty = Boolean.parseBoolean(gitDirty);

            return "built \"" + properties.getProperty("git.build.time") +

                    "\" with short commit id \"" + properties.getProperty("git.commit.id.describe-short") + "\"" +
                    ", isDirty is " + isDirty +
                    " remote url is \"" + properties.getProperty("git.remote.origin.url") + "\"";
        }
        catch( IOException ioe ) {
            return( "can't locate git.properties on the class path");
        }
    }


    private Properties getGitProperties() throws IOException {

        Properties properties = new Properties();

        try (InputStream inputStream = this.getClass().getResourceAsStream("/git.properties")) {
            if (inputStream == null)
                throw new IOException("Can't locate properties file to generate version info");
            properties.load(inputStream);

            return properties;
        }
    }
}
