使用Gradle构建时如何解决“未找到包”错误？

Question

我正在尝试从源代码构建TightVNC Java Viewer（我从此处下载了官方版本： http : //www.tightvnc.com/download.php ）。

使用提供的gradle文件进行构建时，出现此错误：包com.jcraft.jsch不存在。

项目中存在文件“ src / libs / jsch-0.1.50.jar”。 我不知道为什么它不能编译，因为它包含在build.gradle文件中。 我正在使用gradle build命令进行构建。 我想念什么？

这是在gradle包中最初提供的build gradle文件：

apply plugin:'java'
apply plugin: 'eclipse'

sourceCompatibility = 1.6
targetCompatibility = 1.6
version = '2.7.2'

project.ext.baseName = 'tightvnc-jviewer'
def buildNo = processBuildNo(version)

    viewerSwingCompile { extendsFrom compile }
    viewerSwingRuntime { extendsFrom viewerSwingCompile, runtime }

    viewerSwing {
        java {
            srcDir 'src/viewer_swing/java'
        }
        resources {
            srcDir 'src/viewer_swing/resources'
        }
    }
    main {
        java.srcDirs += viewerSwing.java.srcDirs
        resources.srcDirs += viewerSwing.resources.srcDirs
    }
}

repositories {
    flatDir {
        dirs 'src/libs/'
    }
}

    viewerSwingCompile group: 'com.jcraft', name: 'jsch', version: '0.1.+', ext: 'jar'
    viewerSwingRuntime configurations.viewerSwingCompile
    testCompile group: 'junit', name: 'junit', version: '4.+'
}

    def runtimeDeps = configurations.viewerSwingRuntime.collect {
        it.isDirectory() ? it : zipTree(it)
    }
    from(runtimeDeps) {
        exclude 'META-INF/**'
    }
}

task noSshJar (type: Jar, dependsOn: classes) {

        }
    }
    uploadDescriptor = false
}

task dist(dependsOn: uploadArchives)

def processBuildNo(currentVersion) {
    final String VERSION = 'version'
    final String BUILD = 'build'

    def lastVersion = currentVersion
    def lastBuild = 0
    def buildNoFile = new File('.build_no')
    if ( ! buildNoFile.exists()) {
        buildNoFile.createNewFile()
        buildNoFile << "${VERSION}=${lastVersion}\n${BUILD}=${lastBuild}"
    }
    def versions = [:]
    buildNoFile.eachLine {
        def splitted = it.split('=')
        if (splitted.size() == 2) {

                        lastBuild = value != null ? value.trim() as Integer : 0
                    } catch (NumberFormatException) {}
                    versions[lastVersion] = lastBuild
                    break
            }
        }
    }
    lastVersion = versions[currentVersion]
    if (null == lastVersion) {
        versions[currentVersion] = 0
    }
    ++versions[currentVersion]
    def outString = ''
    versions.each { v, b ->
        outString += "${VERSION}=${v}\n${BUILD}=${b}\n\n"
    }
    buildNoFile.write(outString)
    versions[currentVersion]
}

经过大量的反复试验，我添加了：

compile fileTree(dir: 'src/libs', include: '*.jar')

在依赖项部分下，它起作用了！
