Birt Runtime maven artifact issue第一：第二：

java maven report birt
2022-09-04 04:34:05

我想在我的项目中使用Birt Api库，所以我在我的项目中包含rg.eclipse.birt.runtime 4.5 maven依赖项

<dependency>
        <groupId>org.eclipse.birt.runtime</groupId>
        <artifactId>org.eclipse.birt.runtime</artifactId>
        <version>4.5.0</version>
        <exclusions>
            <exclusion>
                <groupId>org.eclipse.birt.runtime</groupId>
                <artifactId>org.eclipse.osgi</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.eclipse.tycho</groupId>
        <artifactId>org.eclipse.osgi</artifactId>
        <version>3.10.100.v20150529-1857</version>
    </dependency>

当我想执行我的报告时，我得到了以下堆栈跟踪错误，这是由“org.eclipse.core.runtime.IExtensionRegistry”的签名者信息与同一包中其他类的签名者信息不匹配引起的。以前，我使用相同的库Birt Runtime 4.5，但手动下载并附加到我的项目中，并且成功生成了报告。

org.eclipse.birt.runtime-4.5.0Maven Central Repository 上的可用取决于使用旧版和新版本的 Eclipse 证书签名的 JAR，但这些 JAR 包含来自同一软件包的类（在本例中）。当从两个 JAR 加载类时，JVM 会因为这种签名不一致而引发此类类。org.eclipse.core.runtimeSecurityException

例如，这可以用 和 作为证据，这两个依赖关系都包含包中的类。中央 Maven 存储库上可用的版本使用不同的证书进行签名，如以下所示：org.eclipse.equinox.common-3.6.200.v20130402-1505.jarorg.eclipse.equinox.registry-3.6.0.v20150318-1503.jarorg.eclipse.birt.runtime-4.5.0org.eclipse.core.runtimejarsigner -verify -verbose -certs xxx.jar

//org.eclipse.equinox.common-3.6.200.v20130402-1505.jar
[entry was signed on 09/04/13 15:24]
X.509, CN="Eclipse.org Foundation, Inc.", OU=IT, O="Eclipse.org Foundation, Inc.", L=Ottawa, ST=Ontario, C=CA

//org.eclipse.equinox.registry-3.6.0.v20150318-1503.jar
[entry was signed on 18/03/15 18:14]
X.509, CN="Eclipse Foundation, Inc.", OU=IT, O="Eclipse Foundation, Inc.", L=Ottawa, ST=Ontario, C=CA

因此，当尝试从两个 JAR 加载类时。您可以：SecurityException

  • 使用版本与 Maven 一起使用4.6.0-20160607
  • 从官方网站手动下载并附加版本，该版本与使用最新证书版本签名的JAR打包4.5.0

附注：可以通过创建具有以下依赖项的 Maven 项目来重现问题：

    <dependency>
        <groupId>org.eclipse.birt.runtime</groupId>
        <artifactId>org.eclipse.birt.runtime</artifactId>
        <version>4.5.0</version>
        <exclusions>
            <exclusion>
                <groupId>org.eclipse.birt.runtime</groupId>
                <artifactId>org.eclipse.osgi</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

运行一个代码，该代码将加载使用不同证书（例如上面引用的证书）签名的JAR中包含的类，例如：

Class.forName("org.eclipse.core.runtime.Assert").getResource("Assert.class");
Class.forName("org.eclipse.core.runtime.IExtensionRegistry").getResource("IExtensionRegistry.class");

使用版本时将导致类似，但不与版本 。SecurityException4.5.04.6.0-20160607

另一个注意事项：版本4.2.0 M7也存在类似的问题。


答案 2

我有2个解决方案。请检查

第一：

使用依赖项版本 4.5.0a 而不是 4.5

<dependency>
<groupId>org.eclipse.birt.runtime</groupId>
<artifactId>org.eclipse.birt.runtime</artifactId>
<version>4.5.0a</version>
</dependency>
