运行“gradle build”时，我们的一个项目出现以下错误，其中几个类出现以下编译错误：

cannot be applied to given types;
                this._logFilter.setFirstResult(firstResult);
                               ^
  required: int
  found: long
  reason: actual argument long cannot be converted to int by method invocation conversion

即使，该方法也setFirstResult需要一个longas 参数。这是代码：

public void setFirstResult(long firstResult) {
    this._firstResult = firstResult;
}

我已经尝试--refresh-dependencies并清除了缓存等。这些都不适合我。此外，这个项目是一个 maven 项目，我将它转换为使用 gradle。

编辑：

根据评论的要求，我在这里添加了额外的上下文：

这里是源代码this._logFilter

public class GlobalMessageLogFilter {
    private long _firstResult = 0L;

    private long _maxResults = 100L;

    private Application _application;

    private SeverityLevelEnum _severityLevel;

    private EnvironmentEnum _environment;

    private String _userName;

    private Category _category;

    public EnvironmentEnum getEnvironment() {
        return this._environment;
    }

    public void setEnvironment(EnvironmentEnum environment) {
        this._environment = environment;
    }

    public long getFirstResult() {
        return this._firstResult;
    }

    public void setFirstResult(long firstResult) {
        this._firstResult = firstResult;
    }

    public long getMaxResults() {
        return this._maxResults;
    }

    public void setMaxResults(long maxResults) {
        this._maxResults = maxResults;
    }

    public Application getApplication() {
        return this._application;
    }

    public void setApplication(Application application) {
        this._application = application;
    }

    public SeverityLevelEnum getSeverityLevel() {
        return this._severityLevel;
    }

    public void setSeverityLevel(SeverityLevelEnum severityLevel) {
        this._severityLevel = severityLevel;
    }

    public String getUserName() {
        return this._userName;
    }

    public void setUserName(String userName) {
        this._userName = userName;
    }

    public Category getCategory() {
        return this._category;
    }

    public void setCategory(Category category) {
        this._category = category;
    }
}

这是完整的堆栈跟踪

编辑：添加源代码GlobalMessageLogProvider

public class GlobalMessageLogProvider extends SortableDataProvider<GlobalMessageLog, String>
{
    @SpringBean
    private GlobalMessageLogRepository _globalMessageLogRepository;
    private GlobalMessageLogFilter _logFilter;
    private boolean _searchAllowed = false;


    public GlobalMessageLogProvider(GlobalMessageLogFilter globalMessageLogFilter)
    {
        Injector.get().inject(this);
        this._logFilter = globalMessageLogFilter;
    }


    @Override
    public Iterator<? extends GlobalMessageLog> iterator(long firstResult, long maxResults)
    {
        this._logFilter.setFirstResult(firstResult);
        this._logFilter.setMaxResults(maxResults);
        Iterator<GlobalMessageLog> results = Arrays.<GlobalMessageLog> asList().iterator();

        if (this._searchAllowed)
        {
            if (super.getSort() == null)
            {
                results = this._globalMessageLogRepository.search(this._logFilter, "id", false).iterator();
            } else
            {
                results =
                        this._globalMessageLogRepository.search(this._logFilter,
                                super.getSort().getProperty(),
                                super.getSort().isAscending()).iterator();
            }
        }
        return results;
    }
}

我发现了这个问题，我能够解决它。大多数评论指出，这setFirstResult(int firstResult)是它使用的错误版本的类。他们是正确的。

基本上，GlobalMessageLogProvider已经改变了，但最新版本的 jar 从未被推送到 Nexus 服务器（我们自己的私有第三方依赖服务器）。所以，每当我把罐子拉下来时，它总是引用旧的。

手动将最新的 jar 推送到 Nexus 服务器后，我能够使用 gradle 成功构建项目而没有错误。

所以从这个问题中解脱出来：我们需要创建一个构建过程，它将自动构建/推送最新版本的 jar 到 Nexus 服务器。我正在考虑使用一些自定义命令/脚本通过我们的 TeamCity 构建服务器创建构建/推送过程。（如果有，请随时提供任何更好的建议/实践技巧）。

感谢大家的热心帮助，我由衷的感谢。
