Question

我想使用maven-jar-plugin来构建diff分类器jar，例如：

mvn deploy：deploy -P debug，classifier-demo-0.0.1-debug.jar已部署

mvn deploy：部署-P test，classifier-demo-0.0.1-test.jar。

但失败：

Execution default of goal org.springframework.boot:spring-boot-maven-plugin:1.2.3.RELEASE:repackage failed: Source must refer to an existing file

Answer 1

目标：重新包装重新打包尝试重新打包原始工件，即projectName.jar。这是maven的默认包阶段的结果，即 mvn package 命令输出。

当Repackage目标执行时，它会尝试查找projectName.jar。

当你运行mvn spring-boot：package时，projectName.jar不在那里。这就是为什么它会给出错误来源必须引用现有文件

解决方案：运行命令 mvn clean package spring-boot：repackage

Answer 2

我想这就是原因：

this.project.getArtifact().getFile()

弹簧引导行家-插件\ SRC \主\的java \有机\ springframework的\引导\行家\ RepackageMojo.java

public void execute() throws MojoExecutionException, MojoFailureException {
    // ......

    File source = this.project.getArtifact().getFile();
    File target = getTargetFile();
    Repackager repackager = new Repackager(source) {
        @Override
        protected String findMainMethod(JarFile source) throws IOException {
            long startTime = System.currentTimeMillis();
            try {
                return super.findMainMethod(source);
            }
            finally {
                long duration = System.currentTimeMillis() - startTime;
                if (duration > FIND_WARNING_TIMEOUT) {
                    getLog().warn(
                            "Searching for the main-class is taking some time, "
                                    + "consider using the mainClass configuration "
                                    + "parameter");
                }
            }
        }
    };
    // ......
}

实际上，如果你设置Spring Boot Maven插件，你已经将spring-boot：repackage包含在包中。所以只需“mvn clean package”就足够了，我们不需要“mvn package spring-boot：repackage”。

目标org.springframework.boot的执行默认值：spring-boot-maven-plugin：1.2.3.RELEASE：repackage failed：Source必须引用现有文件
