Jenkins插件的两个构建步骤之间未共享GlobalConfiguration

Question

我有一个如下所示的全局配置类，其中包含所有全局字段。

@Extension
public class CustomGlobalConfiguration extends GlobalConfiguration {
   /** @return the singleton instance */
 public static CustomGlobalConfiguration get() {
    return GlobalConfiguration.all().get(CustomGlobalConfiguration.class);
}
private String pcip;
private String userName;
private String password;
public CustomGlobalConfiguration() {
    // When Jenkins is restarted, load any saved configuration from disk.
    load();
}
public String getPcip() {
    return pcip;
}
public String getUserName() {
    return userName;
}
public String getPassword() {
    return password;
}
@DataBoundSetter
public void setPcip(String pcip) {
    this.pcip = pcip;
    save();
}
@DataBoundSetter
public void setUserName(String userName) {
    this.userName = userName;
    save();
}
@DataBoundSetter
public void setPassword(String password) {
    this.password = password;
    save();
}

下面是我的两个构建器类，它们试图获取全局值集。但是在第二节课中，这似乎不起作用。

A级

public class IntegrationLeader extends Builder{
private final String blueprintName, appName;
private static final String USER_AGENT = "Mozilla/5.0";
private static final String POST_PARAMS = "{\"length\":250}";

@DataBoundConstructor
public IntegrationLeader(String blueprintName, String appName) {
    this.blueprintName = blueprintName;
    this.appName = appName;
}
// We'll use this from the <tt>config.jelly</tt>.
public String getBlueprintName(){
    return blueprintName;
}
public String getAppName() {
    return appName;
}
@Override
public boolean perform(AbstractBuild build, Launcher launcher, BuildListener listener) throws IOException, InterruptedException {
    EnvVars envVars = new EnvVars();
    final EnvVars env = build.getEnvironment(listener);
    PrintStream log = listener.getLogger();
    //Expanding appname to include the env variables in it's name
    String expandedapp = env.expand(appName);
    String ip = getDescriptor().getCalmIP()
    //rest of the other stuff
}
@Override
public DescriptorImpl getDescriptor() {
    return (DescriptorImpl) super.getDescriptor();
}
@Extension 
public static final class DescriptorImpl extends BuildStepDescriptor<Builder> {
    private String calmIP;
    private String calmUser;
    private String calmPwd;
    public List<String> offers;
    public List<String> profiles;
    public List<String> projects;
    public List<String> actions;
    public DescriptorImpl() {
        load();
    }
    public boolean isApplicable(Class<? extends AbstractProject> aClass) {
        // Indicates that this builder can be used with all kinds of project types
        return true;
    }
    /**
     * This human readable name is used in the configuration screen.
     */
    public String getDisplayName() {
        return "Nutanix Calm Blueprint Launch";
    }
    @Override
    public boolean configure(StaplerRequest req, JSONObject formData) throws FormException {
        CustomGlobalConfiguration calmGlobalConfiguration = CustomGlobalConfiguration.get();
        calmIP = calmGlobalConfiguration.getPcip();
        calmUser = calmGlobalConfiguration.getUserName();
        calmPwd = calmGlobalConfiguration.getPassword();

        save();
        return super.configure(req, formData);
    }
}

B级

public class RunActionOnApp extends Builder{
private final String blueprintName, appName;
private static final String USER_AGENT = "Mozilla/5.0";
private static final String POST_PARAMS = "{\"length\":250}";
// Fields in config.jelly must match the parameter names in the "DataBoundConstructor"
@DataBoundConstructor
public IntegrationLeader(String blueprintName, String appName) {
    this.blueprintName = blueprintName;
    this.appName = appName;
}
// We'll use this from the <tt>config.jelly</tt>.
public String getBlueprintName(){
    return blueprintName;
}
public String getAppName() {
    return appName;
}
@Override
public boolean perform(AbstractBuild build, Launcher launcher, BuildListener listener) throws IOException, InterruptedException {
    EnvVars envVars = new EnvVars();
    final EnvVars env = build.getEnvironment(listener);
    PrintStream log = listener.getLogger();
    //Expanding appname to include the env variables in it's name
    String expandedapp = env.expand(appName);
    String ip = getDescriptor().getCalmIP()
    //rest of the other stuff
}
@Override
public DescriptorImpl getDescriptor() {
    return (DescriptorImpl) super.getDescriptor();
}
@Extension // This indicates to Jenkins that this is an implementation of an extension point.
public static final class DescriptorImpl extends BuildStepDescriptor<Builder> {
    /**
     * To persist global configuration information, simply store it in a
     * field and call save().
     *
     * <p>
     * If you don't want fields to be persisted, use <tt>transient</tt>.
     */
    private String calmIP;
    private String calmUser;
    private String calmPwd;
    public List<String> offers;
    public List<String> profiles;
    public List<String> projects;
    public List<String> actions;
    private int lastEditorId = 0;
    private int lastprofId = 0;
    public DescriptorImpl() {
        load();
    }
    public boolean isApplicable(Class<? extends AbstractProject> aClass) {
        // Indicates that this builder can be used with all kinds of project types
        return true;
    }
    /**
     * This human readable name is used in the configuration screen.
     */
    public String getDisplayName() {
        return "Nutanix Calm Blueprint Launch";
    }
    @Override
    public boolean configure(StaplerRequest req, JSONObject formData) throws FormException {
        // To persist global configuration information,
        // set that to properties and call save().
        CustomGlobalConfiguration calmGlobalConfiguration = CustomGlobalConfiguration.get();
        calmIP = calmGlobalConfiguration.getPcip();
        calmUser = calmGlobalConfiguration.getUserName();
        calmPwd = calmGlobalConfiguration.getPassword();
        // ^Can also use req.bindJSON(this, formData);
        // (easier when there are many fields; need set* methods for this, like setUseFrench)
        save();
        return super.configure(req, formData);
    }
}

正在使用 configure 功能访问全局配置值。该hpi成功创建并上传。如果我使用 IntegrationLeader 添加了构建步骤，则可以完美读取全局配置（因为在api调用之后填充了其他字段，为了进行api调用，我们需要由GlobalConfiguration读取的凭据）。但是，当我使用 RunActionOnApp 添加构建步骤时，由于ip，用户名和密码字段被设置为null，因此api调用开始失败。
